UBUNTU-CVE-2022-49814

In the Linux kernel, the following vulnerability has been resolved: kcm: close race conditions on skreceivequeue sk-skreceivequeue is protected by skb queue lock, but for KCM sockets its RX path takes mux-rxlock to protect more than just skb queue. However, kcmrecvmsg still only grabs the skb que...

CVE-2022-49924

CVE-2022-49924 : In the Linux kernel NFC fdp path, fdp_nci_send() calls fdp_nci_i2c_write() which may not free the skb, causing a memory leak when the I2C write completes. The public impact is a potential memory leak affecting kernel availability (CVSS base 5.5, HIGH for availability) with no imp...

CVE-2022-49923

The CVE affects the Linux kernel nxp-nci path (nfc: nxp-nci: Fix potential memory leak in nxp_nci_send). The root cause is that nxp_nci_send() frees the allocated skb only on nxp_nci_i2c_write() failure; when the write succeeds, nxp_nci_i2c_write() does not free the skb, causing a memory leak. A ...

CVE-2022-49908

CVE-2022-49908 affects the Linux kernel Bluetooth path, where a memory leak could occur in L2CAP/vhci_write: when an ACL fragment lacks the L2CAP length, the HCI core may copy the skb to conn->rx_skb and finish processing without freeing it. The provided patches fix this by releasing the relat...

CVE-2022-49858 octeontx2-pf: Fix SQE threshold checking

In the Linux kernel, the following vulnerability has been resolved: octeontx2-pf: Fix SQE threshold checking Current way of checking available SQE count which is based on HW updated SQB count could result in driver submitting an SQE even before CQE for the previously transmitted SQE at the same...

CVE-2022-49858

The CVE-2022-49858 entry concerns the Linux kernel’s octeontx2-pf driver. A faulty SQE (Submission Queue Entry) threshold check based on HW-updated SQB count could allow submitting an SQE before the CQE for the previous one is processed in NAPI, causing loss of SKB pointers and a leak. The root c...
