In one of the error paths in tw9906_probe(), the memory allocated in v4l2_ctrl_handler_init() and v4l2_ctrl_new_std() is not freed. Fix that by calling v4l2_ctrl_handler_free() on the handler in that error path.

GHSA-2885-GRQH-2673
Vulnerability from github – Published: 2025-01-23 15:31 – Updated: 2025-12-07 00:30
VLAI
Details
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_set_pipapo: fix initial map fill
The initial buffer has to be inited to all-ones, but it must restrict it to the size of the first field, not the total field size.
After each round in the map search step, the result and the fill map are swapped, so if we have a set where f->bsize of the first element is smaller than m->bsize_max, those one-bits are leaked into future rounds result map.
This makes pipapo find an incorrect matching results for sets where first field size is not the largest.
Followup patch adds a test case to nft_concat_range.sh selftest script.
Thanks to Stefano Brivio for pointing out that we need to zero out the remainder explicitly, only correcting memset() argument isn't enough.

Commit 8c0eb596baa5 ("[SCSI] qla2xxx: Fix a memory leak in an error path of qla2x00_process_els()"), intended to change:
bsg_job->request->msgcode == FC_BSG_HST_ELS_NOLOGIN
bsg_job->request->msgcode != FC_BSG_RPT_ELS
but changed it to:
bsg_job->request->msgcode == FC_BSG_RPT_ELS
instead.
Change the == to a != to avoid leaking the fcport structure or freeing unallocated memory.

Vulnerability from github – Published: 2024-07-10 09:30 – Updated: 2024-11-25 21:30
VLAI
Details
In the Linux kernel, the following vulnerability has been resolved:
ipv6: sr: fix missing sk_buff release in seg6_input_core
The seg6_input() function is responsible for adding the SRH into a packet, delegating the operation to the seg6_input_core(). This function uses the skb_cow_head() to ensure that there is sufficient headroom in the sk_buff for accommodating the link-layer header. In the event that the skb_cow_header() function fails, the seg6_input_core() catches the error but it does not release the sk_buff, which will result in a memory leak.
This issue was introduced in commit af3b5158b89d ("ipv6: sr: fix BUG due to headroom too small after SRH push") and persists even after commit 7a3f5b0de364 ("netfilter: add netfilter hooks to SRv6 data plane"), where the entire seg6_input() code was refactored to deal with netfilter hooks.
The proposed patch addresses the identified memory leak by requiring the seg6_input_core() function to release the sk_buff in the event that skb_cow_head() fails.

Vulnerability from github – Published: 2026-05-27 15:33 – Updated: 2026-06-16 15:33

Details
In the Linux kernel, the following vulnerability has been resolved:
rxrpc: Fix memory leaks in rxkad_verify_response()
Fix rxkad_verify_response() to free the ticket and the server key under all circumstances by initialising the ticket pointer to NULL and then making all paths through the function after the first allocation has been done go through a single common epilogue that just releases everything - where all the releases skip on a NULL pointer.
Severity
5.5 (Medium)

Mitigation MIT-41
Implementation
Strategy: Libraries or Frameworks
- Choose a language or tool that provides automatic memory management, or makes manual memory management less error-prone.
- For example, glibc in Linux provides protection against free of invalid pointers.
- When using Xcode to target OS X or iOS, enable automatic reference counting (ARC) [REF-391].
- To help correctly and consistently manage memory when programming in C++, consider using a smart pointer class such as std::auto_ptr (defined by ISO/IEC ISO/IEC 14882:2003), std::shared_ptr and std::unique_ptr (specified by an upcoming revision of the C++ standard, informally referred to as C++ 1x), or equivalent solutions such as Boost.
Mitigation
Architecture and Design
Use an abstraction library to abstract away risky APIs. Not a complete solution.
Mitigation
Architecture and Design
Build and Compilation
Consider using the Boehm-Demers-Weiser garbage collector (bdwgc), which can help avoid leaks.
