CVE-2026-72448
Last modified
CVE-2026-72448 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: octeontx2-pf: Fix leak of SQ timestamp buffer on teardown The send-queue timestamp ring is allocated with qmem_alloc() when timestamping is used, but otx2_free_sq_res() never freed sq->timestamps, leaking that memory across ifdown and device removal. Add the missing qmem_free() alongside the other SQ companion buffers.. EPSS estimates a 0.18% chance of exploitation in the next 30 days.
