All three are missing-check or wrong-allocation problems that lead to a NULL pointer being inserted into an xarray, a heap buffer overflow, or an out-of-bounds write that corrupts the kernel heap. Regards, Tariq Yevgeny Kliteynik (3): net/mlx5: HWS, Handle NULL in vport destination action creation net/mlx5: HWS, Fix heap buffer overflow in insert header action net/mlx5: DR, Fix out-of-bounds write when sync to HW fails .../mellanox/mlx5/core/steering/hws/action.c | 7 +++++- .../mellanox/mlx5/core/steering/hws/fs_hws.c | 3 +++ .../mlx5/core/steering/sws/dr_icm_pool.c | 23 +++++++++++++++++-- 3 files changed, 30 insertions(+), 3 deletions(-) base-commit: b6ef0d965fe8ce0ee4b4dcb58b3511f83003e42d -- 2.44.0
