CVE-2026-98651

The Linux kernel contains a vulnerability in the KVM s390 component where the function page_cond_set_storage_key() improperly handles a NULL pointer passed as oldkey by certain callers. This improper handling leads to a NULL pointer dereference , which can cause system crashes. The issue is resol...

CVE-2026-98651 KVM: s390: Properly handle NULL pointer in dat_cond_set_storage_key()

In the Linux kernel, the following vulnerability has been resolved: KVM: s390: Properly handle NULL pointer in datcondsetstoragekey Some callers pass NULL as oldkey. Calling pagecondsetstoragekey will cause that NULL pointer to get dereferenced. Fix by checking for NULL and assigning the pointer ...

CVE-2026-98641

In the Linux kernel, the following vulnerability has been resolved: bpf, arm64: set up the frame pointer for the exception callback A program acting as exception boundary saves all callee-saved registers, so buildprologue takes the exceptioncb path and never calls pushcalleeregs. That is the only...

CVE-2026-98641

The Linux kernel contains a vulnerability affecting BPF on arm64 architectures. The issue arises when a program acts as an exception boundary and saves all callee-saved registers, causing the kernel to fail to correctly set the frame pointer (BPF_REG_FP) for the exception callback. Because the ca...

CVE-2026-98623

The Linux kernel contains a vulnerability in the drm/nouveau/clk component within the nvkm_clk_ustate_update function. The root cause is a use-after-loop error where the code fails to validate if a pointer is valid after a list_for_each_entry() loop completes without hitting a break. This allows ...

CVE-2026-98621

In the Linux kernel, the following vulnerability has been resolved: net: gue: reject invalid REMCSUM offsets The REMCSUM option carries an absolute checksum start and checksum field offset. gueremcsum passes them to skbremcsumprocess, whose partial path stores offset - start in the u16...

CVE-2026-98621

The Linux kernel contains a vulnerability where the REMCSUM option can cause an integer underflow . The gue_remcsum() function passes an absolute checksum start and field offset to skb_remcsum_process(), which calculates the difference and stores it in a u16 variable. If the offset is less than t...
