GHSA-F25M-F79X-GQ3F

Vulnerability from github – Published: 2024-12-28 12:30 – Updated: 2025-01-14 18:31

Details

In the Linux kernel, the following vulnerability has been resolved:

irqchip/riscv-aplic: Prevent crash when MSI domain is missing

If the APLIC driver is probed before the IMSIC driver, the parent MSI domain will be missing, which causes a NULL pointer dereference in msi_create_device_irq_domain().

Avoid this by deferring probe until the parent MSI domain is available. Use dev_err_probe() to avoid printing an error message when returning -EPROBE_DEFER.

Severity

5.5 (Medium)

GHSA-F26Q-JHC2-X3H8

Vulnerability from github – Published: 2026-05-06 12:30 – Updated: 2026-05-12 21:31

Details

In the Linux kernel, the following vulnerability has been resolved:

net: ethernet: xscale: Check for PTP support properly

In ixp4xx_get_ts_info() ixp46x_ptp_find() is called unconditionally despite this feature only existing on ixp46x, leading to the following splat from tcpdump:

root@OpenWrt:~# tcpdump -vv -X -i eth0 (...) Unable to handle kernel NULL pointer dereference at virtual address 00000238 when read (...) Call trace: ptp_clock_index from ixp46x_ptp_find+0x1c/0x38 ixp46x_ptp_find from ixp4xx_get_ts_info+0x4c/0x64 ixp4xx_get_ts_info from __ethtool_get_ts_info+0x90/0x108 __ethtool_get_ts_info from __dev_ethtool+0xa00/0x2648 __dev_ethtool from dev_ethtool+0x160/0x234 dev_ethtool from dev_ioctl+0x2cc/0x460 dev_ioctl from sock_ioctl+0x1ec/0x524 sock_ioctl from sys_ioctl+0x51c/0xa94 sys_ioctl from ret_fast_syscall+0x0/0x44 (...) Segmentation fault

Check for ixp46x in ixp46x_ptp_find() before trying to set up PTP to avoid this.

To avoid altering the returned error code from ixp4xx_hwtstamp_set() which before this patch was -EOPNOTSUPP, we return -EOPNOTSUPP from ixp4xx_hwtstamp_set() if ixp46x_ptp_find() fails no matter the error code. The helper function ixp46x_ptp_find() helper returns -ENODEV.

Severity

GHSA-F28C-5RX3-M73F

Vulnerability from github – Published: 2023-07-12 09:30 – Updated: 2024-02-15 18:30

Details

A NULL pointer dereference vulnerability was found in netlink_dump. This issue can occur when the Netlink socket receives the message(sendmsg) for the XFRM_MSG_GETSA, XFRM_MSG_GETPOLICY type message, and the DUMP flag is set and can cause a denial of service or possibly another unspecified impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is unlikely.

Severity

6.6 (Medium)

Vulnerability from github – Published: 2022-05-24 19:16 – Updated: 2022-05-24 19:16

Details

While fuzzing the 2.4.49 httpd, a new null pointer dereference was detected during HTTP/2 request processing, allowing an external source to DoS the server. This requires a specially crafted request. The vulnerability was recently introduced in version 2.4.49. No exploit is known to the project.

Severity

7.5 (High)

In the Linux kernel, the following vulnerability has been resolved:

iwlwifi: mvm: check debugfs_dir ptr before use

When "debugfs=off" is used on the kernel command line, iwiwifi's mvm module uses an invalid/unchecked debugfs_dir pointer and causes a BUG:
