Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the possibility that the radeon locking work queue may not be fully flushed...

CVE-2024-26931

A flaw was found in the qla2xxx module in the Linux kernel. A NULL pointer dereference can be triggered when the system is under memory stress and the driver cannot allocate memory to handle the error recovery of cable pull, causing a system crash and a denial of service. Mitigation Mitigation fo...

CVE-2024-27023

In CVE-2024-27023, the Linux kernel md subsystem (md) had a flaw where active_io was not released when flush_pending fell to zero, causing mddev_suspend() to wait forever. The fix releases active_io in submit_flushes() as soon as flush_pending transitions to zero, preventing the hang. The descrip...

CVE-2024-26931

The CVE-2024-26931 issue affects the Linux kernel’s qla2xxx SCSI driver. Under memory pressure, the driver could not allocate an SRB to perform error recovery during a cable pull, causing a flush failure and the upper layer to modify scsi_cmnd. When memory frees up, another cable-pull flush could...
