Hi stable team,
Could you please consider backporting upstream commit
f8d14b7bb0063bbbd86c0e4d73edb8cea7b362bc
("ACPICA: Fix NULL pointer dereference in acpi_ns_custom_package()")
for 6.18.y, 6.12.y, 6.6.y, 6.1.y, 5.15.y, and 5.10.y.
It prevents a NULL pointer dereference when firmware supplies a _BIX
package containing an unresolvable first element.
The fix has been in mainline since May 27 but is still absent from the
longterm branches.
The upstream commit applies cleanly to all of these branches.
Thanks,
Xiang
