CVE-2024-43821

In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Fix a possible null pointer dereference In function lpfcxcvrdatashow, the memory allocation with kmalloc might fail, thereby making rdpcontext a null pointer. In the following context and functions that use this...

The vulnerability of the kmalloc() function in the mm/slub component of the Linux operating system allows a hacker to cause a service failure.

The vulnerability of the kmalloc function in the mm/slub component of the Linux operating system is related to a crash due to insufficient memory. Exploiting this vulnerability can allow an attacker to cause a service failure...

CVE-2024-43854

The CVE-2024-43854 entry relates to the Linux kernel vulnerability where the integrity buffer used for media writes was not zero-initialized. Root cause: metadata allocated by bio_integrity_prep used plain kmalloc, risking writing random kernel memory into media; PI metadata exposure is limited, ...

CVE-2024-43854 block: initialize integrity buffer to zero before writing it to media

In the Linux kernel, the following vulnerability has been resolved: block: initialize integrity buffer to zero before writing it to media Metadata added by biointegrityprep is using plain kmalloc, which leads to random kernel memory being written media. For PI metadata this is limited to the app...
