CVE-2026-99267 Nov 3, 2026 Source: Vendor
In the Linux kernel, the following vulnerability has been resolved:
io_uring/napi: make stale entries time out after 60s
With dynamic tracking a NAPI id that hasn't been seen for a minute is
meant to be dropped from the list the ring busy polls. The timeout is
added to jiffies, but it is defined as 60 * SEC_CONVERSION, and
SEC_CONVERSION isn't the number of jiffies in a second. It is the
internal factor of __timespec64_to_jiffies(), HZ scaled up by
SEC_JIFFIE_SC bits. For HZ=1000 that is 1000
