CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Don't hand out the flat CCS storage as usable VRAM
get_flat_ccs_offset() reads the base of the flat CCS storage from the
hardware, scales it by the number of enabled L3 nodes, and rounds the
result up to 128K. Everything below that offset is then handed to the
VRAM allocator as usable memory.
Rounding a limit that means "usable memory ends here" upwards publishes
whatever lies between the real base and the rounded one as free memory,
and that memory belongs to the compression hardware. The scaled value
has no reason to be 128K aligned, and on a Battlemage G21 with 16 GiB it
is not:
flat CCS base: raw 0x3fafff800, rounded 0x3fb000000
so the last 2 KiB of page 0x3fafff000 is CCS storage, in the allocator's
pool. Whatever is allocated there gets that tail overwritten by the
compression hardware, which needs no page-table entry, no buffer object
and no GPU submission to do it, and does it before userspace exists.
On this machine a Mesa VM's level-3 page table landed on that page on
every cold boot. It lost the entry covering the compositor's
batch-buffer heap, so the compositor's first submission faulted fetching
its batch and gdm restarted it forever: a black screen on an otherwise
working machine. Restarting gdm cleared it because the next VM's page
tables were allocated somewhere else.
Round down instead, to the page size the allocator works in. On this
machine that excludes exactly one page.
Reading the reserved page afterwards shows what had been writing it:
[369] 0xcccc000000000000
[371] 0xcc77000000000000
[373] 0xcccc000000000000
[375] 0xcc77000000000000
compression metadata, two bytes per sixteen, sitting where the driver
used to hand out memory.
The assertion that should have caught this compares the offset against
GSMBASE - ccs_size for equality. That value is 128K aligned, so it
agrees with the rounded-up offset precisely when the base is not
aligned - the check cannot fail in the case it exists to catch, and is
compiled out unless CONFIG_DRM_XE_DEBUG is set. Replace it with one
that can fail: CCS storage must not run into GSM.
[ And this was a debug session from hell, enormously helped by an AI
doing much of the grunt-work.
I'd like to call it my tireless helper, but the AI several times
stated flat out that this was impossible and unsolvable and that we
should just write a report about it.
I suspect those things have been trained by people who may not be
quite as stubborn as I am.
But while the AI was ready to give up several times, it did keep
adding debug code and analyzing it faithfully when I pushed. So credit
where credit is due and I let the AI write the commit message above.
This is basically a one-liner fixing a bogus "round_up()" to a
"round_down()", but there were 24 patches adding more and more debug
information to this, and 18 kernel boot to finally narrow it down to
this. - Linus ] |
| 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. |
| A vulnerability was identified in GPAC 26.08-DEV. This vulnerability affects the function gf_rtp_parse_ttxt of the file src/ietf/rtp_depacketizer.c of the component RTP Depacketizer. Such manipulation of the argument size leads to out-of-bounds read. It is possible to launch the attack remotely. Upgrading to version abi-16.26 is able to resolve this issue. The name of the patch is 6bb0f64b4d1039c0fecd14ee2c1ee861d8661a68. The affected component should be upgraded. |
| PocketSphinx is a small speech recognizer. Prior to 5.1.1, the trie language-model loaders in src/lm/ngram_model_trie.c do not adequately validate boundary conditions in ARPA, DMP, and binary format headers, and the acoustic-model loaders in src/mdef.c and src/util/bio.c use sscanf with unbounded string fields. Loading an invalid, corrupted, or malicious language or acoustic model can therefore cause stack or heap buffer overflows and memory corruption. An attacker who can write to a directory selected by POCKETSPHINX_PATH can replace or add a model file that PocketSphinx later loads; users of PocketSphinx 5prealpha have no backported patch and must migrate to the fixed release. This issue is fixed in version 5.1.1. |
| A vulnerability in the network security monitoring component of intrusion detection systems could allow an unauthenticated remote attacker to exploit a limited buffer overflow. Successful exploitation could allow an attacker to cause a denial-of-service or potentially execute arbitrary code on the system. |
| A vulnerability exists in the configuration processing logic of the affected component where malformed input is improperly processed. An authenticated remote attacker with administrative privileges could exploit this vulnerability by providing specially crafted configuration data. Successful exploitation could result in a stack-based buffer overflow, potentially leading to remote code execution with root privileges or a denial of service due to a system crash. |

| A vulnerability in the RADIUS feature of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
This vulnerability is due to improper handling of certain RADIUS requests. An attacker could exploit this vulnerability by sending a crafted RADIUS request directly to an affected device. A successful exploit could allow the attacker to cause the ISE node to become unavailable. For single node deployments in that condition, endpoints that have not already authenticated would be unable to access the network until the node comes back up on its own. |
