CVE-2021-47058 regmap: set debugfs_name to NULL after it is freed

In the Linux kernel, the following vulnerability has been resolved: regmap: set debugfsname to NULL after it is freed There is a upstream commit cffa4b2122f5"regmap:debugfs: Fix a memory leak when calling regmapattachdev" that adds a if condition when create name for debugfsname. With below...

CVE-2021-47058

CVE-2021-47058 is a Linux kernel vulnerability affecting the regmap debugfs path. The issue arises from a memory leak in which debugfs_name is freed in regmap_debugfs_exit() but not recreated due to a conditional added by upstream commit cffa4b2122f5. The relevant sequence involves regmap_reinit_...

CVE-2023-52488 serial: sc16is7xx: convert from _raw_ to _noinc_ regmap functions for FIFO

In the Linux kernel, the following vulnerability has been resolved: serial: sc16is7xx: convert from raw to noinc regmap functions for FIFO The SC16IS7XX IC supports a burst mode to access the FIFOs where the initial register address is sent $00, followed by all the FIFO data without having to...

CVE-2023-52488

CVE-2023-52488 concerns the Linux kernel driver for SC16IS7XX UARTs. In burst mode, the SC16IS7XX can read/write FIFO data with an initial register address, and regmap_raw_read()/regmap_raw_write() do not increment the register in this path. This could corrupt the regmap cache when multi-byte tra...

The vulnerability of the snd_hdac_regmap_sync() function in the sound/hda/hdac_regmap.c driver of the Linux High-Definition Audio kernel allows a hacker to cause a service failure.

The vulnerability of the sndhdacregmapsync function in the sound/hda/hdacregmap.c driver of the Linux High-Definition Audio kernel is related to the assignment of a null pointer. Exploiting this vulnerability could allow an attacker to cause a service failure...

DEBIAN-CVE-2024-23196

A race condition was found in the Linux kernel's sound/hda device driver in sndhdacregmapsync function. This can result in a null pointer dereference issue, possibly leading to a kernel panic or denial of service issue...

Linux kernel code issue vulnerability

The Linux kernel is the kernel used by the Linux Foundation's open source operating system Linux. A security vulnerability exists in the Linux kernel that stems from a null pointer dereference in the sndhdacregmapsync method of the sound/hda device driver...
