CVE-2024-53049 slub/kunit: fix a WARNING due to unwrapped __kmalloc_cache_noprof

In the Linux kernel, the following vulnerability has been resolved: slub/kunit: fix a WARNING due to unwrapped kmalloccachenoprof 'modprobe slubkunit' will have a warning as shown below. The root cause is that kmalloccachenoprof was directly used, which resulted in no alloctag being allocated. Th...

kernel: Linux kernel: Denial of Service via integer overflow in kmalloc_reserve()

A flaw was found in the Linux kernel's networking subsystem. A local attacker can exploit an integer overflow vulnerability in the kmallocreserve function by manipulating network interface settings. This can cause the kernel to attempt a memory allocation with an incorrect size, leading to memory...

CVE-2024-50165 bpf: Preserve param->string when parsing mount options

In the Linux kernel, the following vulnerability has been resolved: bpf: Preserve param-string when parsing mount options In bpfparseparam, keep the value of param-string intact so it can be freed later. Otherwise, the kmalloc area pointed to by param-string will be leaked as shown below:...

CVE-2024-50087 btrfs: fix uninitialized pointer free on read_alloc_one_name() error

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix uninitialized pointer free on readalloconename error The function readalloconename does not initialize the name field of the passed fscryptstr struct if kmalloc fails to allocate the corresponding buffer. Thus, it is n...

CVE-2024-50087

The connected Astra Linux advisory & the CVE entry describe a Linux kernel vulnerability in btrfs: read_alloc_one_name() may leave fscrypt_str.name uninitialized if kmalloc fails, so freeing fscrypt_str can access an uninitialized pointer. This is a local (L) issue with LOW initial access but HIG...
