CVE-2023-53704

CVE-2023-53704 affects the Linux kernel in clk-imx clock driver paths (e.g., clk-imx8mp/clk-imx8mq). The issue involves memory management during probe/setup, where memory was previously released manually and iounmap’d regions could leak. The published fix replaces of_iomap() and kzalloc() with de...

If xpalloctxdescs fails, and it can only fail due to not having enough memory,...

CVE-2023-53698

In the Linux kernel, the xsk refcount underflow vulnerability was fixed in the error path when xp_alloc_tx_descs() fails due to memory exhaustion. The bug occurred because the pool’s refcount was decremented after being incremented, but xs->pool in the socket was not nulled. As a result, on so...

CVE-2022-50577 ima: Fix memory leak in __ima_inode_hash()

In the Linux kernel, the following vulnerability has been resolved: ima: Fix memory leak in imainodehash Commit f3cc6b25dcc5 "ima: always measure and audit files in policy" lets measurement or audit happen even if the file digest cannot be calculated. As a result, iint-imahash could have been...

CVE-2022-50577

CVE-2022-50577 involves a memory leak in the Linux kernel’s IMA path. The root cause was that __ima_inode_hash() could allocate ima_hash and then fail after ima_collect_measurement() returned an error, allowing a leaked temporary inode metadata structure. The patch adds a kfree() when the error f...

CVE-2022-50575

CVE-2022-50575 concerns the Linux kernel xen/privcmd path where, because kdata.num is user-controlled, an allocation request ≥ MAX_ORDER can fail, triggering a stack trace and a noisy dmesg warning. The underlying issue is an unsafe large allocation warning in privcmd_ioctl_mmap_resource(), which...

CVE-2022-50569

Summary of CVE-2022-50569 (Linux kernel xfrm/ipcomp_scratches): The vulnerability arises when ipcomp_alloc_scratches() fails to allocate per-CPU scratches, leaving ipcomp_scratches with an obsolete address. During ipcomp_free_scratches(), the code frees per-CPU scratch space by iterating CPUs and...
