CVE-2026-89936

CVE-2026-89936 affects the Linux kernel 's iio: dac: m62332 driver (Microchip M62332 DAC). The function m62332_set_value() enables the Vcc regulator on every non-zero channel write and disables it on every zero write, but does not track the channel's prior state. Because the regulator is referenc...

CVE-2026-89902 LoongArch: Avoid preempt count underflow without probe

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Avoid preempt count underflow without probe LoongArch uses break 11 for the breakpoint placed after an instruction that Kprobes executes out of line. Since userspace can issue the same break instruction, dobp can reach...

CVE-2026-89902

This Linux kernel vulnerability affects the LoongArch kprobe subsystem. Because LoongArch uses break 11 for kprobe breakpoints, an ordinary userspace breakpoint can reach kprobe_singlestep_handler() with no active probe. The handler calls preempt_enable_no_resched() before checking for a probe, c...

CVE-2026-89841

CVE-2026-89841 affects the f2fs filesystem in the Linux kernel . The flaw resides in redirty_blocks(), where a do/while loop introduced by commit 5951fee46bef causes an extra iteration when read_cache_folio() fails before any folio is pinned. If readahead has already populated the failed folio in...
