net: strparser: fix skb_head leak in strp_abort_strp()_CVE-2026-46102

{
    "lastseen": "",
    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: strparser: fix skb_head leak in strp_abort_strp()\n\nWhen the stream parser is aborted, for example after a message assembly timeout,\nit can still hold a reference to a partially assembled message in\nstrp->skb_head.\n\nThat skb is not released in strp_abort_strp(), which leaks the partially\nassembled message and can be triggered repeatedly to exhaust memory.\n\nFix this by freeing strp->skb_head and resetting the parser state in the\nabort path. Leave strp_stop() unchanged so final cleanup still happens in\nstrp_done() after the work and timer have been synchronized.",
