CVE-2026-99190: gpiolib: fix memory leak in gpiod_set_array_value_complex() on error paths

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 6.12.115, 68a2cd5381b8d89dc80bd16dd9cc9ca2d5c25e7f, 78189c0e35abbcdab3b8ab0b764d578c02900734.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 6.12.115, 68a2cd5381b8d89dc80bd16dd9cc9ca2d5c25e7f, 78189c0e35abbcdab3b8ab0b764d578c02900734 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: gpiolib: fix memory leak in gpiod_set_array_value_complex() on error paths A drive-by review by Sashiko reports that, after a failed call to gpiochip_set_multiple(), gpiod_set_array_value() returns abruptly, bypassing the freeing of possibly alloced bitmaps, potentially leaking memory. It is an unlikely error path, but is possible. Defer the return code check until after the bitmap_free() block.
