CVSS v3.1 |
| Quarkus REST Data Panache provides a way to automatically generate REST endpoints for data entities. A flaw was found where certain endpoints do not properly check the sort parameter provided by users. This could allow an attacker to learn information they should not have access to or slow down the system by forcing the database to perform complex tasks, potentially causing a denial of service. |
| A flaw was found in the Quarkus Qute template engine. When the {#eval} section helper processes a sub-template, it fails to pass the parent template's content type information. This bypasses standard escaping mechanisms, allowing untrusted data to be output as raw, unescaped text. This vulnerability can lead to Cross-Site Scripting (XSS) and JSON Injection, potentially allowing a remote attacker to execute arbitrary code in a user's browser or manipulate data. |
| A flaw was found in RESTEasy's CorsFilter, which, when configured to allow all origins ("*"), reflects the request's Origin header back in the Access-Control-Allow-Origin response together with Access-Control-Allow-Credentials: true. This permissive cross-origin policy allows a malicious website to make credentialed cross-origin requests and read authenticated responses from a victim's session, resulting in a loss of confidentiality. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: don't warn when an IBSS has no channel to scan
ieee80211_request_ibss_scan() warns when regulatory leaves no
allowed channel, but that can happen as the regdomain can change
while IBSS is operating, and it can continue to operate briefly
during the 60s grace period until it's shut down.
Just remove the warning in this case. |
| Untrusted pointer dereference in Microsoft Office PowerPoint allows an unauthorized attacker to disclose information over a network. |
| In the Linux kernel, the following vulnerability has been resolved:
ipv4: validate checksum_start before completing checksum
If a packet with bad checksum metadata gets into the ipv4 stack,
skb_checksum_help can corrupt the network header and cause a bunch of
mischief.
This was discovered and reported by Paulos, and has been reporoduced
by others independently since.
We really shouldn't allow such packets in, but as a defence
in depth measure, let's also check before we complete the checksum.
A more complete validation at input is forthcoming, but needs more work. |

s390/crypto: Fix skcipher_walk return code handling in aes_s390
The return codes from skcipher_walk_virt() were not properly checked
before entering the processing loops in ecb_aes_crypt() and ctr_aes_crypt().
If skcipher_walk_virt() fails, the walk structure may be in an undefined
state, and attempting to process data could lead to incorrect behavior
or accessing uninitialized memory.
Add proper return code checking to ensure correct handling of the walk
initialization and walk advance and eventually return to the caller
with that return code. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: skip gfx switch_power_profile during GPU reset
During resume from GPU reset, the gfx idle work may invoke switch_power_profile
before the reset completes. This causes the following assert error because the
register access occurs without first releasing the GPU reset semaphore:

| In the Linux kernel, the following vulnerability has been resolved:
x86/amd_node: Avoid divide by zero on virtualized systems
On a virtualized system, the number of nodes does not have a relationship to
the number of roots. A Xen PVH dom0 can calculate roots_per_node as 0, which
crashes with a divide by zero in:
if (count++ % roots_per_node)
because the underlying topology code on Xen ends up making num_nodes
2 and num_roots 1 and the integer division result is 0.
The issue is seen with Xen, but it could affect other systems.
Set roots_per_node to 1 in this case. Print a firmware bug when this is
performed for non-virtualized systems.

| In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Guard page-fault worker with runtime PM check
During VM teardown, the VM's runtime PM reference is dropped
asynchronously, allowing the device to autosuspend while stale page
faults belonging to the now-dead VM are still queued. When the
page-fault worker later tries to ack one of these, it calls into
guc_ct_send_locked() on an already-suspended device, tripping:
Assertion `!xe_pm_runtime_suspended(xe)` failed!
WARNING at xe_device.c:1267 xe_device_assert_mem_access+0x11c/0x140 [xe]
A live VM/exec queue always holds a PM reference while it has
outstanding work, so if the device is suspended at ack time, the
owning context is already gone and the fault is stale.
Take a runtime PM reference across the entire pagefault
queue worker to safely deliver acks for torn-down VMs.
v3:
- Move PM ref to the generic xe_pagefault_queue_work using
guard(xe_pm_runtime)(xe) instead of tracking it in the GuC
backend(Matt Brost).
v2:
- Hold PM ref across the entire batch (begin/end) instead of per-ack.
This prevents the device from autosuspending mid-batch, which would
leave write_only acks written but the end flush skipped, and skip
counter++, desyncing the cadence check.(Himal)
- Add a comment explaining stale faults.(Himal)

| In the Linux kernel, the following vulnerability has been resolved:
powerpc/entry: Fix irq_soft_mask corruption on replayed interrupt exit
When __replay_soft_interrupts() replays a pending interrupt (e.g.
PACA_IRQ_DEC -> timer_interrupt), it calls the handler directly with a
synthetic pt_regs. The DEFINE_INTERRUPT_HANDLER_ASYNC wrapper around
each handler calls arch_interrupt_async_exit_prepare() on the way out,
which calls arch_interrupt_exit_prepare() -> local_irq_disable() ->
arch_local_irq_disable(), which does:
irq_soft_mask_set(IRQS_DISABLED) /* 0x1 */
This unconditionally overwrites irq_soft_mask with IRQS_DISABLED (0x1),
stripping the IRQS_PMI_DISABLED (0x2) bit. The result is that
irq_soft_mask is 0x1 instead of IRQS_ALL_DISABLED (0x3) when the
handler returns to __replay_soft_interrupts().
For a normally-taken interrupt this is harmless: the next interrupt
always enters through arch_interrupt_enter_prepare() which
unconditionally sets irq_soft_mask to IRQS_ALL_DISABLED. But during
replay, next_interrupt() is called directly between replayed handlers
without going back through arch_interrupt_enter_prepare(), so the
stripped bit is never restored. next_interrupt() then fires a WARNING:
WARNING: arch/powerpc/kernel/irq_64.c:75
WARN_ON(irq_soft_mask_return() != IRQS_ALL_DISABLED)
The warning was observed early in boot on a POWER10 pseries guest
during kmem_cache_init_late(), where a spinlock release triggers
interrupt replay that processes a pending timer interrupt.
Debugger state confirming the bug:
Before timer_interrupt(®s):
irq_soft_mask = 0x3 (IRQS_ALL_DISABLED) correct
irq_happened = 0x41 (HARD_DIS|REPLAYING) correct
After timer_interrupt(®s) returns:
irq_soft_mask = 0x1 (IRQS_DISABLED) WRONG - PMI bit stripped
irq_happened = 0x41 unchanged
The fix is to replace local_irq_disable() with hard_irq_disable().
hard_irq_disable() is the right primitive here for two reasons:
1. On PPC64 (hw_irq.h:301) it calls irq_soft_mask_set_return(IRQS_ALL_DISABLED),
setting the soft mask to 0x3 (both IRQS_DISABLED and IRQS_PMI_DISABLED),
which preserves the PMI bit and fixes the WARNING. The additional
work it does (__hard_irq_disable(), PACA_IRQ_HARD_DIS |=) is
redundant but safe since both are already set at this point in the
exit path; the trace_hardirqs_off() inside is guarded by
if (!arch_irqs_disabled_flags(flags)) so it will not double-fire.
2. On PPC32 (hw_irq.h:467) hard_irq_disable() maps to
arch_local_irq_disable() -> __hard_irq_disable(), which clears
MSR[EE] in hardware. This is exactly correct: PPC32 has no soft-mask
PACA mechanism, so the hardware disable is the right way to satisfy
irqentry_exit()'s requirement. This also fixes a build error on PPC32
where irq_soft_mask_set() is only defined under CONFIG_PPC64:
arch/powerpc/include/asm/entry-common.h:273: error: implicit
declaration of function 'irq_soft_mask_set'
Using hard_irq_disable() requires no #ifdef and is consistent with
how the rest of the entry code (e.g. entry-common.h:463) handles the
same PPC32/PPC64 split. |

powerpc: Do not restore KUAP in arch_exit_to_user_mode_prepare()
KUAP means kernel cannot touch user memory unless it explicitly is
enabled. In the kernel it should stay AMR_KUAP_BLOCKED. While returning
to userspace just before RFI, kernel should restore the user AMR value
back.
Looks like GENERIC_ENTRY might be treating arch_exit_to_user_mode_prepare()
as the last architecture step before returning to userspace.
commit bee25f97ad24 ("powerpc: Enable GENERIC_ENTRY feature")
therefore called kuap_user_restore() from that hook. But on PowerPC that
is too early. After irqentry_exit() / syscall_exit_to_user_mode() we
still run platform specific exit routines.
e.g. code snippets showing both exception handling and system call
handling as the callers of function arch_exit_to_user_mode_prepare()
which does kuap_user_restore(). The below path shows that calling
kuap_user_restore() is too early when called from
arch_exit_to_user_mode_prepare().
Exception handling in exceptions-64s.S
=======================================
bl CFUNC(do_page_fault)
..DEFINE_INTERRUPT_HANDLER_ASYNC(do_page_fault)
arch_interrupt_async_enter_prepare(regs);
state = irqentry_enter(regs);
instrumentation_begin();
irq_enter_rcu();
handler(regs);
nap_adjust_return(regs);
irq_exit_rcu();
instrumentation_end();
arch_interrupt_async_exit_prepare(regs);
irqentry_exit(regs, state); <<< too early
irqentry_exit_to_user_mode()
__exit_to_user_mode_prepare(regs, EXIT_TO_USER_MODE_WORK_IRQ);
arch_exit_to_user_mode_prepare(regs, ti_work); <<< too early
b interrupt_return_srr
.. bl CFUNC(interrupt_exit_user_prepare) <<< already calls kuap_user_restore
prep_irq_for_enabled_exit() retry can run kernel code with IRQs on. So
only when that routine is fully finished is when the user KUAP should be
fully restored which interrupt_exit_user_prepare() already takes care of
before returning.
Similarly for system call handling in interrupt_64.S
======================================================
bl CFUNC(system_call_exception)
.Lsyscall_exit:
addi r4,r1,STACK_INT_FRAME_REGS
li r5,0 /* !scv */
bl CFUNC(syscall_exit_prepare)
.. kuap_assert_locked();
syscall_exit_to_user_mode(regs); <<< too early
syscall_exit_to_user_mode_prepare(regs); <<< too early
kuap_user_restore(regs); <<< already calls
syscall_exit_prepare(), which can enable IRQs, replay a pending
interrupt, and only then rfi. Those functions already restore KUAP
immediately before rfi.
Note that if we restore the user AMR too early like in the current code
as shown from the code snippets above, then we get the following warning
when CONFIG_PPC_KUAP_DEBUG is enabled:

s390/boot: Avoid IPL parameter append past command line
A command line may occupy all but the terminating byte of
COMMAND_LINE_SIZE. In that case append_ipl_block_parm() passes a zero size
to the IPL parameter conversion helpers and points the destination one
byte past early_command_line. The helpers subtract one from the unsigned
size and write the converted parameter outside the command line buffer.
Convert the IPL parameter in the command line parsing buffer first. A
parameter beginning with '=' can then replace the existing command line
regardless of its length, while other parameters are appended only when
space remains. |
