CVE-2026-80560

This Linux kernel vulnerability affects the OpenRISC (or1k) architecture signal handling path. The function restore_sigcontext() copies the entire supervision register (SR) from a user-controlled signal frame and only clears the SPR_SR_SM bit before reloading it into hardware. All other privilege...

CVE-2026-80560

In the Linux kernel, the following vulnerability has been resolved: openrisc: signal: do not restore privileged SR bits on sigreturn restoresigcontext copies the whole supervision register SR from the signal frame and only clears SPRSRSM before the value is reloaded into the hardware SR through E...

CVE-2026-80559

CVE-2026-80559 is a Linux kernel vulnerability in the sur40 input driver. The root cause is an incorrect registration ordering in sur40_probe(): input_register_device() was called before the V4L2 video device and vb2_queue were fully initialized. If userspace opened the input device immediately, ...

CVE-2026-80558

This Linux kernel vulnerability affects the libceph subsystem. A corrupted osdmap received from a Ceph monitor or OSD may contain OSD indices in its primary_temp field that are greater than max_osd or smaller than CEPH_HOMELESS_OSD (-1). While most OSD indices in the osdmap are validated, the one...

CVE-2026-80557

CVE-2026-80557 is a 4-byte out-of-bounds read in the Linux kernel's libceph client, specifically in decode_watchers(). The function calls ceph_decode_32(p) without a preceding bounds check; when a malicious or compromised OSD sends an obj_list_watch_response_t with struct_len=0, the pointer equal...
