UBUNTU-CVE-2022-50167

In the Linux kernel, the following vulnerability has been resolved: bpf: fix potential 32-bit overflow when accessing ARRAY map element If BPF array map is bigger than 4GB, element pointer calculation can overflow because both index and elemsize are u32. Fix this everywhere by forcing 64-bit...

UBUNTU-CVE-2022-50168

In the Linux kernel, the following vulnerability has been resolved: bpf, x86: fix freeing of not-finalized bpfprogpack syzbot reported a few issues with bpfprogpack 1, 2. This only happens with multiple subprogs. In jitsubprogs, we first call bpfintjitcompile on each sub program. And then, we cal...

CVE-2022-50036

CVE-2022-50036 affects the Linux kernel component drm/sun4i: dsi. The underflow occurred when computing packet sizes due to subtracting packet overhead with unsigned arithmetic; with a short sync pulse the subtraction could wrap to a large unsigned value. The remediation is a fix that uses signed...

CVE-2022-50036 drm/sun4i: dsi: Prevent underflow when computing packet sizes

In the Linux kernel, the following vulnerability has been resolved: drm/sun4i: dsi: Prevent underflow when computing packet sizes Currently, the packet overhead is subtracted using unsigned arithmetic. With a short sync pulse, this could underflow and wrap around to near the maximal u16 value. Fi...

CVE-2022-49975

CVE-2022-49975 affects the Linux kernel’s BPF path, where a redirect of packets with invalid pkt_len could occur. The root cause is described as a BPF program test/run path (bpf_prog_test_run_skb) redirecting empty skbs, leading to a potential flow handling issue in fq_codel_drop(). The vulnerabi...

CVE-2022-49975 bpf: Don't redirect packets with invalid pkt_len

In the Linux kernel, the following vulnerability has been resolved: bpf: Don't redirect packets with invalid pktlen Syzbot found an issue 1: fqcodeldrop try to drop a flow whitout any skbs, that is, the flow-head is null. The root cause, as the 2 says, is because that bpfprogtestrunskb run a bpf...

CVE-2022-49972

CVE-2022-49972 concerns a Linux kernel XDP_SHARED_UMEM issue where packets could be corrupted when multiple sockets bind to the same umem (except the first). Root cause: the DMA addresses for pre-populated xsk buffer pool entries were initialized only for the first socket bound to the umem; the l...

CVE-2022-49972 xsk: Fix corrupted packets for XDP_SHARED_UMEM

In the Linux kernel, the following vulnerability has been resolved: xsk: Fix corrupted packets for XDPSHAREDUMEM Fix an issue in XDPSHAREDUMEM mode together with aligned mode where packets are corrupted for the second and any further sockets bound to the same umem. In other words, this does not...

CVE-2025-38053

Summary: A Linux kernel vulnerability (CVE-2025-38053) affects the idpf_features_check path used to validate TX skb features. The root cause is a NULL vport pointer in the netdev private structure after reset, which can lead to a kernel NULL pointer dereference when comparing skb header length wi...
