| There is a Stack overflow Vulnerability in the device Search and Discovery feature of Hikvision Access Control Products. If exploited, an attacker on the same local area network (LAN) could cause the device to malfunction by sending specially crafted packets to an unpatched device. |
| A vulnerability was identified in the email parsing library due to improper handling of specially formatted recipient email addresses. An attacker can exploit this flaw by crafting a recipient address that embeds an external address within quotes. This causes the application to misdirect the email to the attacker's external address instead of the intended internal recipient. This could lead to a significant data leak of sensitive information and allow an attacker to bypass security filters and access controls. |
| A flaw was found in the X.org server. Due to improperly tracked allocation size in _XkbSetCompatMap, a local attacker may be able to trigger a buffer overflow condition via a specially crafted payload, leading to denial of service or local privilege escalation in distributions where the X.org server is run with root privileges. |
| A flaw was found in Keycloak. Keycloak's Security Assertion Markup Language (SAML) broker endpoint does not properly validate encrypted assertions when the overall SAML response is not signed. An attacker with a valid signed SAML assertion can exploit this by crafting a malicious SAML response. This allows the attacker to inject an encrypted assertion for an arbitrary principal, leading to unauthorized access and potential information disclosure. |

ALSA: ctxfi: Fix potential OOB access in audio mixer handling
In the audio mixer handling code of ctxfi driver, the conf field is
used as a kind of loop index, and it's referred in the index callbacks
(amixer_index() and sum_index()).
As spotted recently by fuzzers, the current code causes OOB access at
those functions.
| UBSAN: array-index-out-of-bounds in /build/reproducible-path/linux-6.17.8/sound/pci/ctxfi/ctamixer.c:347:48
| index 8 is out of range for type 'unsigned char [8]'
After the analysis, the cause was found to be the lack of the proper
(re-)initialization of conj field.
This patch addresses those OOB accesses by adding the proper
initializations of the loop indices. |
| Delta Electronics CNCSoft-G2 lacks proper validation of the user-supplied file. If a user opens a malicious file, an attacker can leverage this vulnerability to execute code in the context of the current process. |
| A flaw was found in uv. This vulnerability allows an attacker to execute malicious code during package resolution or installation via specially crafted ZIP (Zipped Information Package) archives that exploit parsing differentials, requiring user interaction to install an attacker-controlled package. |

| In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix out-of-bounds access in sysfs attribute read/write
Some f2fs sysfs attributes suffer from out-of-bounds memory access and
incorrect handling of integer values whose size is not 4 bytes.
For example:
vm:~# echo 65537 > /sys/fs/f2fs/vde/carve_out
vm:~# cat /sys/fs/f2fs/vde/carve_out
65537
vm:~# echo 4294967297 > /sys/fs/f2fs/vde/atgc_age_threshold
vm:~# cat /sys/fs/f2fs/vde/atgc_age_threshold
1
carve_out maps to {struct f2fs_sb_info}->carve_out, which is a 8-bit
integer. However, the sysfs interface allows setting it to a value
larger than 255, resulting in an out-of-range update.
atgc_age_threshold maps to {struct atgc_management}->age_threshold,
which is a 64-bit integer, but its sysfs interface cannot correctly set
values larger than UINT_MAX.
The root causes are:
1. __sbi_store() treats all default values as unsigned int, which
prevents updating integers larger than 4 bytes and causes out-of-bounds
writes for integers smaller than 4 bytes.
2. f2fs_sbi_show() also assumes all default values are unsigned int,
leading to out-of-bounds reads and incorrect access to integers larger
than 4 bytes.
This patch introduces {struct f2fs_attr}->size to record the actual size
of the integer associated with each sysfs attribute. With this
information, sysfs read and write operations can correctly access and
update values according to their real data size, avoiding memory
corruption and truncation. |

netfs: Fix early read unlock of page with EOF in middle
The read result collection for buffered reads seems to run ahead of the
completion of subrequests under some circumstances, as can be seen in the
following log snippet:
9p_client_res: client 18446612686390831168 response P9_TREAD tag 0 err 0
...
netfs_sreq: R=00001b55[1] DOWN TERM f=192 s=0 5fb2/5fb2 s=5 e=0

netfs_collect_stream: R=00001b55[0:] cto=5fb2 frn=ffffffff

...
netfs_sreq: R=00001b55[2] ZERO SUBMT f=000 s=5fb2 0/4e s=0 e=0
netfs_sreq: R=00001b55[2] ZERO TERM f=102 s=5fb2 4e/4e s=5 e=0
The 'cto=5fb2' indicates the collected file pos we've collected results to
so far - but we still have 0x4e more bytes to go - so we shouldn't have
collected folio ix=00005 yet. The 'ZERO' subreq that clears the tail
happens after we unlock the folio, allowing the application to see the
uncleared tail through mmap.
The problem is that netfs_read_unlock_folios() will unlock a folio in which
the amount of read results collected hits EOF position - but the ZERO
subreq lies beyond that and so happens after.
Fix this by changing the end check to always be the end of the folio and
never the end of the file.
In the future, I should look at clearing to the end of the folio here rather
than adding a ZERO subreq to do this. On the other hand, the ZERO subreq can
run in parallel with an async READ subreq. Further, the ZERO subreq may still
be necessary to, say, handle extents in a ceph file that don't have any
backing store and are thus implicitly all zeros.
This can be reproduced by creating a file, the size of which doesn't align
to a page boundary, e.g. 24998 (0x5fb2) bytes and then doing something
like:
xfs_io -c "mmap -r 0 0x6000" -c "madvise -d 0 0x6000" \
-c "mread -v 0 0x6000" /xfstest.test/x
The last 0x4e bytes should all be 00, but if the tail hasn't been cleared
yet, you may see rubbish there. This can be reproduced with kafs by
modifying the kernel to disable the call to netfs_read_subreq_progress()
and to stop afs_issue_read() from doing the async call for NETFS_READAHEAD.
Reproduction can be made easier by inserting an mdelay(100) in
netfs_issue_read() for the ZERO-subreq case.
AFS and CIFS are normally unlikely to show this as they dispatch READ ops
asynchronously, which allows the ZERO-subreq to finish first. 9P's READ op is
completely synchronous, so the ZERO-subreq will always happen after. It isn't
seen all the time, though, because the collection may be done in a worker
thread. |

wifi: mac80211: correctly decode TTLM with default link map
TID-To-Link Mapping (TTLM) elements do not contain any link mapping
presence indicator if a default mapping is used and parsing needs to be
skipped.
Note that access points should not explicitly report an advertised TTLM
with a default mapping as that is the implied mapping if the element is
not included, this is even the case when switching back to the default
mapping. However, mac80211 would incorrectly parse the frame and would
also read one byte beyond the end of the element. |
