CVE-2026-9728 TOCTOU race in mbox_send syscall verifier allows userspace to leak kernel memory

The userspace syscall verifier zvrfymboxsend in drivers/mbox/mboxhandlers.c validated the nested msg-data/msg-size fields by reading them directly out of live userspace memory, and then forwarded the original, still-mutable userspace struct mboxmsg pointer to zimplmboxsend and the underlying...

CVE-2026-74584

This vulnerability affects the Linux kernel 's RDMA/bnxt_re driver (Broadcom NetXtreme RDMA). The root cause is that bnxt_re_alloc_ucontext() allocates the shared page uctx->shpg via __get_free_page(GFP_KERNEL), which does not zero the page, unlike other shared pages in the same driver that co...

In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: Free BPID bitmap on setup failure nixsetupbpids allocates bp-bpids with rvuallocbitmap, which uses a plain kcalloc. If any of the following devmkcalloc allocations for the BPID mapping arrays fails, the function...

CVE-2026-74415

In the Linux kernel, the following vulnerability has been resolved: spi: atcspi200: fix use-after-free when driver unbind DMA resource is initialized after SPI controller registration. So when driver unbind, this can trigger a use-after-free when DMA is torn down while the controller is still ali...

CVE-2026-72101

The CVE-2026-72101 involves the Linux kernel dm‑integrity module. A bug caused zeroing of the remaining space to fail when the hash size was smaller than the device tuple size, leading to leaking uninitialized kernel memory. The issue has been fixed by a commit that corrects the zeroing behavior....
