In the Linux kernel, the following vulnerability has been resolved: tracing: Free histogram the field rejected for a bad modifier Writing a hist trigger whose value or variable carries a modifier that is not allowed there leaks the fields that were...

In the Linux kernel, the following vulnerability has been resolved: tracing: Free histogram var refs regardless of how often they are referenced Using the same variable three or more times in one hist trigger leaks the variable reference and its st...

In the Linux kernel, the following vulnerability has been resolved: tracing: Keep the entry count when the histogram stats allocation fails print_entries() uses n_entries both as the number of sort entries and as its own return value, so the -ENOME...

In the Linux kernel, the following vulnerability has been resolved: tracing: Undo the registration when enabling the histogram trigger fails Commit 6f86bdeab633 ("tracing: Fix bad hist from corrupting named_triggers list") described how a trigger t...

In the Linux kernel, the following vulnerability has been resolved: tracing: Take the reference before publishing the named histogram trigger event_hist_trigger_named_init() puts the trigger on the global named_triggers list and only then takes the...

In the Linux kernel, the following vulnerability has been resolved: accel/ivpu: Validate full buffer range in ivpu_to_cpu_addr Add a size parameter to ivpu_to_cpu_addr() and validate that the whole [vpu_addr, vpu_addr + size) range stays within the...

In the Linux kernel, the following vulnerability has been resolved: accel/ivpu: Limit firmware log name prints to field size The name in struct vpu_tracing_buffer_header is a fixed-size array populated by the NPU firmware. It is expected to be NUL-...

In the Linux kernel, the following vulnerability has been resolved: accel/ivpu: Validate firmware log buffer metadata The tracing log headers parsed by fw_log_print_buffer() reside in DMA-shared BOs that the NPU firmware can write to. fw_log_from_...

In the Linux kernel, the following vulnerability has been resolved: accel: ethosu: Fix ethosu_job_open() return value A WARN_ON() returns a 0 or 1, not the original negative errno. Just drop the WARN_ON() as the FD open will pass the return code to...

In the Linux kernel, the following vulnerability has been resolved: accel: ethosu: Ensure SRAM size is 0 on mapping failure On a mapping failure of the SRAM, the SRAM size is left as non-zero. The probe will succeed as the error return is not check...
