In the Linux kernel, the following vulnerability has been resolved: drivers/amd/pm: fix a use-after-free in kv_parse_power_table When ps allocated by kzalloc equals to NULL, kv_parse_power_table frees adev->pm.dpm.ps that allocated before. However, after the control flow goes through the following call chains: kv_parse_power_table |-> kv_dpm_init |-> kv_dpm_sw_init |-> kv_dpm_fini The adev->pm.dpm.ps is used in the for loop of kv_dpm_fini after its first free in kv_parse_power_table and causes a use-after-free bug.

CVE-2026-867137.1 ALT—
——0PX4 Autopilot through 1.17.0 contains a use-after-free vulnerability in the load_mon module's stop path where exit_and_cleanup() deletes the LoadMon object and frees the performance counter before perf_end() attempts to access it. Attackers can trigger this vulnerability by issuing the load_mon stop command from any PXH or MAVLink shell, causing reads and writes through freed memory that corrupt heap objects and destabilize the flight stack.5hCVE-2026-864253.3 BAJ—
——0ImageMagick before 7.1.2-30 and 6.9.x before 6.9.13-55 contains a heap-use-after-free vulnerability in the Layer method of PerlMagick. An attacker who supplies a crafted list of images can trigger memory access after deallocation, resulting in a crash (denial of service).1dCVE-2026-864233.3 BAJ—
——0ImageMagick before 7.1.2-30 and 6.9.x before 6.9.13-55 contains a heap-use-after-free vulnerability in the GetList method of PerlMagick. A crafted call to the GetList method can trigger the use-after-free, resulting in a crash (denial of service).1dCVE-2026-82325——
