CVE-2024-57943

CVE-2024-57943 affects the Linux kernel exFAT path where a newly allocated buffer head could write uninitialized data from the page cache. The root cause is that buffers marked as new were not zeroed before write_end(), risking data leakage or corruption. The remediation is a kernel commit that c...

CVE-2024-57943 exfat: fix the new buffer was not zeroed before writing

In the Linux kernel, the following vulnerability has been resolved: exfat: fix the new buffer was not zeroed before writing Before writing, if a bufferhead marked as new, its data must be zeroed, otherwise uninitialized data in the page cache will be written. So this commit uses foliozeronewbuffe...

kernel: platform/chrome: cros_ec_chardev: fix kernel data leak from ioctl

In the Linux kernel, the following vulnerability has been resolved: platform/chrome: crosecchardev: fix kernel data leak from ioctl It is possible to peep kernel page's data by providing larger insize in struct croseccommand1 when invoking EC host commands. Fix it by using zeroed memory. 1:...

kernel: block: initialize integrity buffer to zero before writing it to media

A flaw was found in the Linux kernel, where it initialized the integrity buffer to zero before writing it to media. Metadata added by biointegrityprep uses plain kmalloc, which leads to random kernel memory being written. Protection Information PI metadata is limited to the app tag not used by...

kernel: lib/generic-radix-tree.c: Fix rare race in __genradix_ptr_alloc()

A flaw was found in the Linux kernel. A race condition in the genradixptralloc function, responsible for allocating nodes in the generic radix tree, can occur when increasing the tree depth. This race can lead to a preallocated node retaining a pointer to an old root instead of being properly...
