CVE-2026-74664 net: openvswitch: reallocate update replies for mismatched IDs

In the Linux kernel, the following vulnerability has been resolved: net: openvswitch: reallocate update replies for mismatched IDs ovsflowcmdnew preallocates the optional reply skb before it takes ovsmutex and before it knows which existing flow will be updated. That is normally fine because the...

SUSE CVE-2026-72234

In the Linux kernel, the following vulnerability has been resolved: batman-adv: access unicastttvn skb-data only after skb realloc The pskbmaypull called by batadvgetvid could reallocate the buffer behind the skb. Variables which were pointing to the old buffer need to be reassigned to avoid an...

Zoo Design Studio: Memory-corruption in memory handling of lib-kcl

A race condition in kcl-lib can result in a use-after-free when accessing environments concurrently. During Vec reallocation, the previous buffer containing Box pointers is freed and replaced. A concurrent getenv operation that has already loaded a pointer to the old buffer may subsequently index...

CVE-2026-72235

A flaw was found in the Linux kernel batman-adv component. The batadvinterfacerx function, responsible for handling network packets, can reallocate its internal buffer. However, a pointer to the ethernet header is not correctly updated after this reallocation. This oversight leads to a...

CVE-2026-72233

A flaw was found in the batman-adv component of the Linux kernel. This vulnerability occurs when a buffer is reallocated, but existing pointers are not updated, leading to a use-after-free condition. A local attacker could potentially exploit this to cause a system crash denial of service or, in...

CVE-2026-74570

A flaw was found in the Linux kernel's NTFS file system driver. This vulnerability arises from insufficient size calculations during runlist memory reallocation, which could lead to an integer overflow. An attacker could potentially exploit this to cause memory corruption, leading to system...

Unity Linux 20.1070e Security Update: expat (UTSA-2026-099471)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-099471 advisory. In libexpat before 2.8.2, there is a heap-based buffer overflow in doProlog in xmlparse.c because scaffold backing array reallocation is mishandled when there is...
