CVE-2023-53592

In CVE-2023-53592, the Linux kernel GPIO driver for sifive contains a refcount leak in sifive_gpio_probe. Specifically, of_irq_find_parent() returns a node pointer with an incremented refcount, and the bug fixes by ensuring of_node_put() is called when the pointer is no longer needed. The fix pre...

CVE-2023-53592 gpio: sifive: Fix refcount leak in sifive_gpio_probe

In the Linux kernel, the following vulnerability has been resolved: gpio: sifive: Fix refcount leak in sifivegpioprobe ofirqfindparent returns a node pointer with refcount incremented, We should use ofnodeput on it when not needed anymore. Add missing ofnodeput to avoid refcount leak...

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftsetrbtree: fix null deref on element insertion There is no guarantee that rbprev will not return NULL in nftrbtreegcelem: general protection fault, probably for non-canonical address 0xdffffc0000000003: 0000 1 PREEM...

CVE-2023-53542 ARM: dts: exynos: Use Exynos5420 compatible for the MIPI video phy

In the Linux kernel, the following vulnerability has been resolved: ARM: dts: exynos: Use Exynos5420 compatible for the MIPI video phy For some reason, the driver adding support for Exynos5420 MIPI phy back in 2016 wasn't used on Exynos5420, which caused a kernel panic. Add the proper compatible...

CVE-2023-53542

The CVE-2023-53542 issue affects the Linux kernel (ARM/Exynos) where the MIPI video PHY support for Exynos5420 was not using the correct Exynos5420 compatible, leading to a kernel panic. The description states that the fix is to use the proper compatible for Exynos5420, effectively patching the d...

CVE-2023-53538 btrfs: insert tree mod log move in push_node_left

In the Linux kernel, the following vulnerability has been resolved: btrfs: insert tree mod log move in pushnodeleft There is a fairly unlikely race condition in tree mod log rewind that can result in a kernel panic which has the following trace: 530.569 BTRFS critical device sda3: unable to find...

CVE-2023-53538

CVE-2023-53538 affects the Linux kernel via a race in btrfs tree modification log rewind that can lead to a kernel NULL pointer dereference and potential crash. The issue arises during logical inode resolution as a tree mod log rewind processes a sequence of moves/removes/adds and may overwrite m...
