In the Linux kernel, the following vulnerability has been resolved: wifi: rtw89: coex: check NULL return of kmalloc in btcfwsetmonreg kmalloc may fail, return value might be NULL and will cause NULL pointer dereference. Add check NULL return of kmalloc in btcfwsetmonreg...

kernel: udmabuf: change folios array from kmalloc to kvmalloc

A flaw was found in the Linux kernel's udmabuf driver. This vulnerability allows a local user to cause a denial of service DoS by requesting large buffer allocations. Because the driver relies on physically contiguous memory allocations with strict size limits, requesting buffers that exceed kern...

kernel: mm, slub: avoid zeroing kmalloc redzone

In the Linux kernel, the following vulnerability has been resolved: mm, slub: avoid zeroing kmalloc redzone Since commit 946fa0dbf2d8 "mm/slub: extend redzone check to extra allocated kmalloc space than requested", setting origsize treats the wasted space objectsize - origsize as a redzone. Howev...

kernel: scsi: lpfc: Fix a possible null pointer dereference

A flaw was found in the Linux kernel. A local attacker with elevated privileges could exploit a null pointer dereference vulnerability within the scsi: lpfc component. This occurs when memory allocation fails in the lpfcxcvrdatashow function, causing a critical pointer to become null. Subsequent...
