CVE-2026-46261

CVE-2026-46261 relates to the Linux kernel wpcm-fiu SPI driver. The issue is a potential NULL pointer dereference when platform_get_resource_byname() returns NULL, if the NULL is dereferenced by resource_size(). The patch moves the fiu->memory_size assignment to occur after the error check for...

CVE-2026-52938

CVE-2026-52938 concerns a race in Linux kernel BPF storage: bpf_selem_unlink_nofail() clears smap before removal, allowing a concurrent reader in bpf_sk_storage_clone() to observe a NULL smap and dereference a NULL pointer, potentially crashing the kernel (DoS). Reports describe a null-ptr-deref ...

CVE-2026-52959

The CVE-2026-52959 issue affects the Linux kernel SEV guest module. During an extended guest request (SVM_VMGEXIT_EXT_GUEST_REQUEST), get_ext_report() allocates a buffer for a host certificate blob and stores its size in report_req->certs_len. The host may return SNP_GUEST_VMM_ERR_INVALID_LEN ...
