kernel: net/sched: act_api: fix possible infinite loop in tcf_idr_check_alloc()

A vulnerability was found in the Linux kernel's networking subsystem in the actapi implementation within the tcfidrcheckalloc function, which lead to a possible infinite loop when multiple actions with the same index are added, causing the second request to block indefinitely while holding the...

kernel: ext4: do not create EA inode under buffer lock

A vulnerability was found in the Linux kernel's ext4 filesystem, where the system could create EA inodes while holding a buffer lock, this approach can lead to deadlocks, especially if the filesystem is corrupted...

kernel: ext4: fix uninitialized ratelimit_state->lock access in __ext4_fill_super()

A vulnerability was found in the Linux kernel's ext4 filesystem within the ext4fillsuper function, where uninitialized access to ratelimitstate-lock can occur, where the sysfs interface is registered before properly initializing rs-lock, potentially allowing other processes to modify rs-interval ...

A vulnerability was found in the Linux kernel's ext4 filesystem within the ext4fillsuper function, where uninitialized access to ratelimitstate-lock can occur, where the sysfs interface is registered before properly initializing rs-lock, potentially allowing other processes to modify rs-interval ...

kernel: x86/apic: Don't disable x2APIC if locked

In the Linux kernel, the following vulnerability has been resolved: x86/apic: Don't disable x2APIC if locked The APIC supports two modes, legacy APIC or xAPIC, and Extended APIC or x2APIC. X2APIC mode is mostly compatible with legacy APIC, but it disables the memory-mapped APIC interface in favor...

kernel: filelock: fix potential use-after-free in posix_lock_inode

A use-after-free vulnerability was found in the Linux kernel in traceposixlockinode. This issue occurred when the request pointer was changed to point to a lock entry added to the inode's list. Before the tracepoint could fire, another task raced in and freed the lock...

kernel: fs/proc: do_task_stat: use sig->stats_lock to gather the threads/children stats

A vulnerability was found in the dotaskstat function in the Linux kernel, where due to excessive lock contention, a potential hard lockup could be created. This can create a performance bottleneck and lead to kernel unresponsiveness...

kernel: powerpc/eeh: avoid possible crash when edev->pdev changes

In the Linux kernel, the following vulnerability has been resolved: powerpc/eeh: avoid possible crash when edev-pdev changes If a PCI device is removed during eehpereportedev, edev-pdev will change and can cause a crash, hold the PCI rescan/remove lock while taking a copy of edev-pdev-bus...
