Improper Isolation or Compartmentalization in the stream cache mechanism for some Intel(R) Processors may allow an authenticated user to potentially enable escalation of privilege via local access.

Improper input validation in the UEFI WheaERST module for some Intel(R) reference platforms may allow an escalation of privilege. System software adversary with a privileged user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

Improper input validation in the Linux kernel-mode driver for some Intel(R) 800 Series Ethernet before version 1.17.2 may allow an authenticated user to potentially enable escalation of privilege via local access.

Due to the design of the name constraint checking algorithm, the processing time of some inputs scale non-linearly with respect to the size of the certificate. This affects programs which validate arbitrary certificate chains.

In the Linux kernel, the following vulnerability has been resolved: mm: fix zswap writeback race condition The zswap writeback mechanism can cause a race condition resulting in memory corruption, where a swapped out page gets swapped in with data that was written to a different page. The race unfolds like this: 1. a page with data A and swap offset X is stored in zswap 2. page A is removed off the LRU by zpool driver for writeback in zswap-shrink work, data for A is mapped by zpool driver 3. user space program faults and invalidates page entry A, offset X is considered free 4. kswapd stores page B at offset X in zswap (zswap could also be full, if so, page B would then be IOed to X, then skip step 5.) 5. entry A is replaced by B in tree->rbroot, this doesn't affect the local reference held by zswap-shrink work 6. zswap-shrink work writes back A at X, and frees zswap entry A 7. swapin of slot X brings A in memory instead of B The fix: Once the swap page cache has been allocated (case ZSWAPSWAPCACHENEW), zswap-shrink work just checks that the local zswapentry reference is still the same as the one in the tree. If it's not the same it means that it's either been invalidated or replaced, in both cases the writeback is aborted because the local entry contains stale data. Reproducer: I originally found this by running stress overnight to validate my work on the zswap writeback mechanism, it manifested after hours on my test machine. The key to make it happen is having zswap writebacks, so whatever setup pumps /sys/kernel/debug/zswap/writtenbackpages should do the trick. In order to reproduce this faster on a vm, I setup a system with ~100M of available memory and a 500M swap file, then running stress --vm 1 --vm-bytes 300000000 --vm-stride 4000 makes it happen in matter of tens of minutes. One can speed things up even more by swinging /sys/module/zswap/parameters/maxpoolpercent up and down between, say, 20 and 1; this makes it reproduce in tens of seconds. It's crucial to set --vm-stride to something other than 4096 otherwise stress won't realize that memory has been corrupted because all pages would have the same data.

A buffer overflow vulnerability in function gnuspecial in file cplus-dem.c in BinUtils 2.26 allows attackers to cause a denial of service via crafted PE file.

Quadratic complexity when parsing some invalid inputs in encoding/pem

Due to the design of the name constraint checking algorithm, the processing time of some inputs scale non-linearly with respect to the size of the certificate. This affects programs which validate arbitrary certificate chains.

When SNMP is configured on F5OS Appliance and Chassis systems, undisclosed requests can cause an increase in SNMP memory resource utilization.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

A vulnerability exists in F5OS-A and F5OS-C systems that may allow an authenticated attacker with local access to escalate their privileges.  A successful exploit may allow the attacker to cross a security boundary.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

CVE-2024-42516 - this is the "complete" fix for the CVE-2023-38709 response splitting issue. The patch issued upstream for CVE-2023-38709 did not fix the vulnerability.

On F5OS, an improper authorization vulnerability exists where remotely authenticated users (LDAP, RADIUS, TACACS+) may be authorized with higher privilege F5OS roles.

When running in appliance mode, an authenticated attacker assigned the Administrator or Resource Administrator role may be able to bypass Appliance mode restrictions utilizing system diagnostics tcpdump command utility on a F5OS-A/C system.

Validating the order of the public keys in the Diffie-Hellman Key Agreement Protocol, when an approved safe prime is used, allows remote attackers (from the client side) to trigger unnecessarily expensive server-side DHE modular-exponentiation calculations. The client may cause asymmetric resource consumption. The basic attack scenario is that the client must claim that it can only communicate with DHE, and the server must be configured to allow DHE and validate the order of the public key.

A use-after-free vulnerability in the Linux kernel's netfilter: nftables component can be exploited to achieve local privilege escalation.

The nftverdictinit() function allows positive values as drop error within the hook verdict, and hence the nfhookslow() function can cause a double free vulnerability when NFDROP is issued with a drop error which resembles NFACCEPT.

We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660.

A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from the response times of ciphertexts with correct PKCS#1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack in the RSA-PSK key exchange, potentially leading to the leakage of sensitive data. CVE-2024-0553 is designated as an incomplete resolution for CVE-2023-5981.
