net: seeq: Fix use after free vulnerability in ether3 Driver Due to Race Condition
Noroxi assessment
Priority: Monitor (action score 28/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.22% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
- Fixed version: Linux Linux 1c57d61a43293252ad732007c7070fdb112545fd, 25d559ed2beec9b34045886100dac46d1ad92eba, 338a0582b28e69460df03af50e938b86b4206353; Azure Linux 3.0 ARM 6.6.56.1-5; Azure Linux 3.0 x64 6.6.56.1-5.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to Linux Linux 1c57d61a43293252ad732007c7070fdb112545fd, 25d559ed2beec9b34045886100dac46d1ad92eba, 338a0582b28e69460df03af50e938b86b4206353; Azure Linux 3.0 ARM 6.6.56.1-5; Azure Linux 3.0 x64 6.6.56.1-5 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
In the Linux kernel, the following vulnerability has been resolved: net: seeq: Fix use after free vulnerability in ether3 Driver Due to Race Condition In the ether3_probe function, a timer is initialized with a callback function ether3_ledoff, bound to &prev(dev)->timer. Once the timer is started, there is a risk of a race condition if the module or device is removed, triggering the ether3_remove function to perform cleanup. The sequence of operations that may lead to a UAF bug is as follows: CPU0 CPU1 | ether3_ledoff ether3_remove | free_netdev(dev); | put_devic | kfree(dev); | | ether3_outw(priv(dev)->regs.config2 |= CFG2_CTRLO, REG_CONFIG2); | // use dev Fix it by ensuring that the timer is canceled before proceeding with the cleanup in ether3_remove.
