CVE-2023-52436

CVE-2023-52436 affects the Linux kernel in the f2fs file system. The issue arises when setting an extended attribute (xattr) because the xattr list was not guaranteed to be zeroed in unused space; the fix explicitly terminates the xattr list to avoid relying on zeroed unused space. The descriptio...

CVE-2023-52464

CVE-2023-52464 affects the Linux kernel EDAC/thunderx driver. The issue is a potential out-of-bounds string access in thunderx_ocx_com_threaded_isr due to repeated use of strncat with an incorrect buffer size, which mimics a strlcat-like pattern but uses the wrong bound. The root cause is the mis...

CVE-2021-46935

CVE-2021-46935 : Linux kernel binder vulnerability where async_free_space accounting for empty parcels leaked up to 8 bytes per 8-byte-or-smaller async transaction. Root cause: after a patch fixing visibility (Android binder buffer moved out of user space), the free operation didn’t add back size...

CVE-2021-46953

The CVE-2021-46953 issue affects the Linux kernel ACPI GTDT driver. If a probe fails due to invalid firmware properties, the driver may unmap an interrupt it mapped earlier without verifying that the mapping succeeded, and if the firmware reports an interrupt number overlapping the GIC SGI range,...

CVE-2021-46938

CVE-2021-46938 affects the Linux kernel in the device-mapper (dm-mq) path for request-based mapped devices. When loading a device-mapper table, if the allocation/initialization of blk_mq_tag_set for the device fails, a subsequent dev_remove can trigger a double free during cleanup because the poi...

CVE-2021-46921

CVE-2021-46921 affects the Linux kernel’s locking/qrwlock code. The vulnerability arises in queued_write_lock_slowpath while the wait_lock is held: a reader can observe values before the writer has truly acquired the lock, due to an ordering gap between atomic_cond_read_acquire() and the subseque...

CVE-2021-46933

The CVE-2021-46933 issue affects the Linux kernel USB gadget f_fs component. It occurred when ffs_data_clear was invoked indirectly via ffs_fs_kill_sb/ffs_ep0_release, causing eventfd_ctx_put to be called multiple times and leading to a refcount underflow. The documented fix zeroes out ffs_eventf...

CVE-2021-46934

CVE-2021-46934 affects the Linux kernel i2c subsystem, specifically the compat ioctl path.
