CVE-2026-90310

CVE-2026-90310 affects the Linux kernel 's xen/xenbus driver. A race condition exists where the xenstore watch thread (xenwatch ) can trigger xenbus_dev_changed() before the otherend_id field is initialized during device probe (e.g., on module load). The still-zeroed otherend_id is then misinterp...

CVE-2026-90286 drm/amdgpu/gfx6: Use PFP on the compute queues too

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/gfx6: Use PFP on the compute queues too On GFX6, the compute rings use the same CP path as the graphics ring. The only difference is that they don't support draw commands. As opposed to GFX7 and newer which have a...

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Remove redundant VPD flash read in sysfs read path qla2x00sysfsreadvpd called ha-ispops-readoptrom a second time after releasing optrommutex. The repeated read is redundant and, unlike the first, runs without...

CVE-2026-90285

This Linux kernel vulnerability affects the scsi qla2xxx driver. In qla2x00_sysfs_read_vpd(), a redundant second call to ha->isp_ops->read_optrom() is made after releasing optrom_mutex , unlike the first call which holds the mutex. This exposes the flash read to concurrent optrom operations...

CVE-2026-90284

This Linux kernel vulnerability affects the firmware_loader subsystem, specifically the fw_load_sysfs_fallback() function. A race condition exists because device_add() publishes the sysfs loading interface before the firmware request is added to pending_fw_head. A userspace helper discovering the...

CVE-2026-90264

CVE-2026-90264 is a race condition in the Linux kernel's btrfs filesystem that can cause a kernel BUG/panic . The bug occurs when a direct IO finishes short: the file's isize is reverted, which skips the ordered extent (OE) wait during subsequent buffered writeback. This allows a new OE to be ins...
