Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: strparser: fix skb_head leak in strp_abort_strp()<br /> <br /> When the stream parser is aborted, for example after a message assembly timeout,<br /> it can still hold a reference to a partially assembled message in<br /> strp-&gt;skb_head.<br /> <br /> That skb is not released in strp_abort_strp(), which leaks the partially<br /> assembled message and can be triggered repeatedly to exhaust memory.<br /> <br /> Fix this by freeing strp-&gt;skb_head and resetting the parser state in the<br /> abort path. Leave strp_stop() unchanged so final cleanup still happens in<br /> strp_done() after the work and timer have been synchronized.
