kernel: xfrm: policy: fix use-after-free on inexact bin in xfrm_policy_bysel_ctx()

A flaw was found in the Linux kernel. A race condition exists in the xfrm policy handling, specifically within the xfrmpolicybyselctx function. This flaw allows for a use-after-free vulnerability, where memory is accessed after it has been released. This can lead to system instability or a denial...

kernel: xfrm: fix stale skb->prev after async crypto steals a GSO segment

A flaw was found in the Linux kernel's xfrm subsystem. This vulnerability arises when asynchronous cryptographic operations incorrectly handle network packet segments, leaving a pointer to memory that has already been released. An attacker could potentially exploit this use-after-free condition t...

kernel: xfrm: hold dev ref until after transport_finish NF_HOOK

A flaw was found in the Linux kernel's xfrm IP eXtensible FRamework subsystem. This vulnerability involves a race condition where a network device's reference is released too early during packet processing after asynchronous cryptography. This premature release can lead to the system attempting t...

kernel: xfrm: input: hold netns during deferred transport reinjection

A flaw was found in the Linux kernel's xfrm input component. The transport-mode reinjection process, which handles network packet re-injection, stores a network namespace pointer that must remain valid until a deferred callback completes. However, a missing reference count for the network namespa...
