  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nocteontx2-pf: Fix leak of SQ timestamp buffer on teardown\n\nThe send-queue timestamp ring is allocated with qmem_alloc() when\ntimestamping is used, but otx2_free_sq_res() never freed sq->timestamps,\nleaking that memory across ifdown and device removal.  Add the missing\nqmem_free() alongside the other SQ companion buffers.",
