| In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: return early from a zero-length flush
SYNC_BO does not constrain its size, so a request for zero bytes reaches
drm_clflush_virt_range(), which ends with an unconditional
clflushopt(end - 1). For an empty range that is the byte before the
mapping, and abo->mem.kva comes from vmap(), so the access lands in the
guard page below the vmalloc area and faults:
BUG: unable to handle page fault for address: ffffd16fbbc70fff
#PF: supervisor read access in kernel mode
Oops: Oops: 0000 [#1] SMP NOPTI
CPU: 7 UID: 1000 Comm: sync_bo_probe
RIP: 0010:drm_clflush_virt_range+0x3c/0x70
Call Trace:
amdxdna_drm_sync_bo_ioctl+0x124/0x430 [amdxdna]
drm_ioctl+0x301/0x4c0
__x64_sys_ioctl+0x115/0x2f0
do_syscall_64+0xa6/0x3d0
Any process that can open the render node can do this. Reproduced 3 of 3
times on a Strix Point NPU (1022:17f0), by calling SYNC_BO with size 0 on
an AMDXDNA_BO_SHARE object. The import arm takes the same request but
flushes the whole scatterlist, so it survives it.
Nothing needs flushing for an empty range, so answer before choosing a
path. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Correctly handle end of VA space TLBI invalidation
Our TLB invalidation by VA code is based on comparing two ranges,
one defined by the TLB, and one defined by the TLBI instruction.
Each range is defined by a start and a size. However, the way the
comparison is done doesn't account for address rollover, as it
compares an address with (base + size). This works nicely until
this expression represent the last page/block in the TTBR1 VA space,
as the result is a big fat 0. And a failed TLB invalidation.
Rewrite the comparison in a way that is immune to the address
rollover (making the end address inclusive instead of exclusive),
and move this into a common helper that is used by both VA and IPA
invalidations, as suggested by Hyunwoo Kim (although the IPA version
didn't suffer from this particular problem, obviously). |
| In the Linux kernel, the following vulnerability has been resolved:
media: tda18250: fix possible integer overflow
Integer overflow may occur, when variable exp equals to zero. Result
of shift 1 << (exp - 1) may then leads to undefined behavior. |
| In the Linux kernel, the following vulnerability has been resolved:
media: s2255: bound JPEG frame size before copying into the buffer
s2255_fillbuff() memcpy()s vc->jpg_size bytes of a captured JPEG/MJPEG
frame into the vb2 plane. vc->jpg_size is taken verbatim from the
S2255_MARKER_FRAME header the device sends (pdword[4] in save_frame())
and, unlike the frame payload length just above it, is never bounded:
payload = le32_to_cpu(pdword[3]);
if (payload > vc->req_image_size) /* payload is checked ... */
return -EINVAL;
vc->pkt_size = payload;
vc->jpg_size = le32_to_cpu(pdword[4]); /* ... jpg_size is not */
A malicious or malfunctioning device can therefore report a jpg_size
larger than the destination vb2 plane, and the memcpy() writes past it.
jpg_size is a signed int, so a value with the top bit set also turns
into a huge length.
Reject a frame whose jpg_size is negative or exceeds the plane size
before copying it. |
| In the Linux kernel, the following vulnerability has been resolved:
media: rtl2832_sdr: release URBs and stream buffers on start_streaming() failure
rtl2832_sdr_start_streaming() calls rtl2832_sdr_alloc_stream_bufs(),
rtl2832_sdr_alloc_urbs() and rtl2832_sdr_submit_urbs() in sequence and
shares a single err: label that only unlocks the mutex and returns.
When alloc_urbs() succeeds but submit_urbs() fails, or when alloc_urbs()
itself returns -ENOMEM after alloc_stream_bufs() has already succeeded,
the URBs and/or the coherent DMA stream buffers stay allocated while
streaming reports failure to vb2. Two latent defects follow on the next
VIDIOC_STREAMON:
1) rtl2832_sdr_alloc_stream_bufs() unconditionally resets dev->buf_num
to 0 and overwrites dev->buf_list[]/dev->dma_addr[], permanently
leaking the coherent DMA memory allocated by the previous attempt.
2) rtl2832_sdr_alloc_urbs() never resets dev->urbs_initialized and only
increments it. After a second successful pass urbs_initialized can
exceed MAX_BULK_BUFS, so the subsequent rtl2832_sdr_free_urbs() walks
from urbs_initialized - 1 down to 0 and reads past the end of
dev->urb_list[], passing garbage pointers to usb_free_urb().
Mirror the teardown that stop_streaming() already performs: on the error
path call rtl2832_sdr_free_urbs() and rtl2832_sdr_free_stream_bufs()
before unlocking. Both helpers are idempotent (free_urbs kills and zeros
urbs_initialized; free_stream_bufs is gated on URB_BUF and clears the
buf_num counter), so partial-failure paths and the no-allocation paths
remain safe.

| Out-of-bounds read in Windows Win32K - GRFX allows an authorized attacker to elevate privileges locally. |
| PraisonAI is a multi-agent teams system. Prior to 0.1.6, praisonai_platform/services/auth_service.py assigns the public dev-secret-change-me value to JWT_SECRET when PLATFORM_JWT_SECRET is unset, and its production guard does not run when PLATFORM_ENV is also unset because that setting defaults to dev. A remote unauthenticated attacker can mint an HS256 token with an arbitrary sub and email, and the platform's AuthService._verify_token() and get_current_user dependency accept the forged identity for protected API routes. This vulnerability is fixed in praisonai-platform 0.1.6. |

| Multiple Cisco products are affected by a vulnerability in the Snort 3 HTTP Decoder that could allow an unauthenticated, remote attacker to cause the disclosure of possible sensitive data or cause the Snort 3 Detection Engine to crash.
This vulnerability is due to an error in the logic of buffer handling when the MIME fields of the HTTP header are parsed. This can result in a buffer under-read. An attacker could exploit this vulnerability by sending crafted HTTP packets through an established connection that is parsed by Snort 3. A successful exploit could allow the attacker to induce one of two possible outcomes: the unexpected restarting of the Snort 3 Detection Engine, which could cause a denial of service (DoS) condition, or information disclosure of sensitive information in the Snort 3 data stream. Due to the under-read condition, it is possible that sensitive information that is not valid connection data could be returned. |
| A vulnerability in the web UI of Cisco IOS Software could allow an authenticated, remote attacker with low privileges to cause a denial of service (DoS) condition on an affected device.
This vulnerability is due to improper input validation. An attacker could exploit this vulnerability by sending a crafted URL in an HTTP request. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. |
