Input: evdev - fix information leak in evdev_pass_values()

Noroxi assessment

Priority: Monitor (action score 0/100)

  • 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: 0.17% (FIRST EPSS).
  • Fixed version: Linux Linux 06a286b320236508d02ab2ccc9496352748652a8, 7d17e9454a9af3ec7aebb88b41a9deedd5b19a6b, 7e55ca1080f09d9f7112c7f20ac31f682c1f2374; azl3 kernel 6.6.150.1-1 on Azure Linux 3.0 6.6.152.1-1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 06a286b320236508d02ab2ccc9496352748652a8, 7d17e9454a9af3ec7aebb88b41a9deedd5b19a6b, 7e55ca1080f09d9f7112c7f20ac31f682c1f2374; azl3 kernel 6.6.150.1-1 on Azure Linux 3.0 6.6.152.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: Input: evdev - fix information leak in evdev_pass_values() In evdev_pass_values(), the input_event structure is allocated on the kernel stack and populated field-by-field. However, it is never fully initialized. On architectures where struct input_event contains explicit or implicit padding (such as the 32-bit __pad field on SPARC64), these padding bytes are left uninitialized. When this event structure is subsequently passed to the client buffer and later copied to userspace, the uninitialized padding bytes leak kernel stack memory, potentially exposing sensitive information. Similar issues exist in __evdev_queue_syn_dropped and __pass_event. Fix this by explicitly zeroing the entire event structure with memset() before populating its fields. This ensures all padding bytes are cleared before the data crosses the security boundary.
