Descripción
*** Pendiente de traducción *** 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->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->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.
