CVE-2026-46102 Details
Description
In the Linux kernel, the following vulnerability has been resolved: net: strparser: fix skb_head leak in strp_abort_strp() When the stream parser is aborted, for example after a message assembly timeout, it can still hold a reference to a partially assembled message in strp->skb_head. That skb is not released in strp_abort_strp(), which leaks the partially assembled message and can be triggered repeatedly to exhaust memory. Fix this by freeing strp->skb_head and resetting the parser state in the abort path. Leave strp_stop() unchanged so final cleanup still happens in strp_done() after the work and timer have been synchronized.
A memory leak vulnerability has been identified in the Linux kernel's stream parser component. When the stream parser is aborted, such as after a message assembly timeout, it can retain a reference to a partially assembled message in 'strp->skb_head'. This reference is not released during the abortion process, leading to a memory leak. The issue can be exploited repeatedly, causing memory exhaustion. The vulnerability affects the Linux kernel stable tree.
Users can upgrade to the latest version of the Linux kernel stable tree, where this vulnerability has been addressed.
