In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix possible UAF in amdgpu_cs_pass1() Since the gang_size check is outside of chunk parsing loop, we need to reset i before we free the chunk data.

In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_reject_ipv6: fix potential crash in nf_send_reset6() I got a syzbot report without a repro [1] crashing in nf_send_reset6() I think the issue is that dev->hard_header_len is zero, and we attempt later to push an Ethernet header. Use LL_MAX_HEADER, as other functions in net/ipv6/netfilter/nf_reject_ipv6.c.
