As a result, when fdp_nci_i2c_write() finished, the skb will memleak. fdp_nci_send() should free skb after fdp_nci_i2c_write() finished. The Linux kernel CVE team has assigned CVE-2022-49924 to this issue. Affected and fixed versions =========================== Issue introduced in 4.4 with commit a06347c04c13e380afce0c9816df51f00b83faf1 and fixed in 5.10.154 with commit e8c11ee2d07f7c4dfa2ac0ea8efc4f627e58ea57 Issue introduced in 4.4 with commit a06347c04c13e380afce0c9816df51f00b83faf1 and fixed in 5.15.78 with commit 44bc1868a4f542502ea2221fe5ad88ca66d1c6b6 Issue introduced in 4.4 with commit a06347c04c13e380afce0c9816df51f00b83faf1 and fixed in 6.0.8 with commit 1a7a898f8f7b56c0eaa2baf67a0c96235a30bc29 Issue introduced in 4.4 with commit a06347c04c13e380afce0c9816df51f00b83faf1 and fixed in 6.1 with commit 8e4aae6b8ca76afb1fb64dcb24be44ba814e7f8a Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions.

Affected files ============== The file(s) affected by this issue are: drivers/nfc/fdp/fdp.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/e8c11ee2d07f7c4dfa2ac0ea8efc4f627e58ea57 https://git.kernel.org/stable/c/44bc1868a4f542502ea2221fe5ad88ca66d1c6b6 https://git.kernel.org/stable/c/1a7a898f8f7b56c0eaa2baf67a0c96235a30bc29 https://git.kernel.org/stable/c/8e4aae6b8ca76afb1fb64dcb24be44ba814e7f8a
