openssl: invalid pointer dereference in CMP server via crafted protectionAlg

A flaw was found in OpenSSL. A crafted CMP Certificate Management Protocol message can cause an invalid pointer dereference due to a missing type check in the password-based protection verification. A remote, unauthenticated attacker can crash applications acting as a CMP server or client,...

CVE-2026-89749

A flaw was found in the Linux kernel. Specifically, within the tracing subsystem, the eventteststuff function can pass an invalid error pointer to kthreadstop if kthreadrun fails to create a kernel thread. This improper handling of error pointers, particularly under memory pressure, leads to...

CVE-2026-80993

A flaw was found in the Linux kernel's net: phylink component. The phylinkinbandcaps function does not correctly validate the return value from macselectpcs, which can return an error pointer instead of a valid Physical Coding Sublayer PCS object. This oversight can lead to dereferencing an inval...

CVE-2026-80838

CVE-2026-80838 affects the vxlan subsystem in the Linux kernel. The root cause is a race condition during a filtered bulk FDB flush: vxlan_fdb_dst_destroy() unlinks the last remote from a non-nexthop FDB entry before the parent entry is removed from the hash table. During this window, an RCU read...
