Vulnerability from github – Published: 2024-02-27 21:31 – Updated: 2024-04-10 21:30

Details

In the Linux kernel, the following vulnerability has been resolved:

sfc: farch: fix TX queue lookup in TX flush done handling

We're starting from a TXQ instance number ('qid'), not a TXQ type, so efx_get_tx_queue() is inappropriate (and could return NULL, leading to panics).

Severity ?

5.5 (Medium)
