In the Linux kernel, the following vulnerability has been resolved: mISDN: fix possible memory leak in mISDNregisterdevice Afer commit 1fa5ae857bb1 "driver core: get rid of struct device's busid string array", the name of device is allocated dynamically, add putdevice to give up the reference, so...

CVE-2022-49909

The connected advisories describe CVE-2022-49909 as a Linux kernel Bluetooth L2CAP use-after-free (A2MP) in l2cap_conn_del(). When l2cap_recv_frame() processes data and creates an A2MP channel that is not held, the reference counting can reach 1, and during hci_error_reset(), l2cap_chan_unlock() ...

CVE-2022-49822

The CVE refers to a Linux kernel CIFS issue: when tlink setup fails, connections may not be released, causing a refcount leak in the CIFS module and leaking fscache info, which can lead to errors on subsequent mounts (e.g., CIFS: Cache volume key already in use). The vulnerability is tied to the ...

CVE-2022-49822 cifs: Fix connections leak when tlink setup failed

In the Linux kernel, the following vulnerability has been resolved: cifs: Fix connections leak when tlink setup failed If the tlink setup failed, lost to put the connections, then the module refcnt leak since the cifsd kthread not exit. Also leak the fscache info, and for next mount with fsc, it...

CVE-2022-49787

Summary (CVE-2022-49787): In the Linux kernel, the mmc: sdhci-pci fix prevents a memory leak by ensuring proper PCI device reference counting. The root cause is that pci_get_device() increases the pci_dev reference count and may not be balanced with pci_dev_put() before amd_probe() returns; the f...

CVE-2025-37779

CVE-2025-37779 concerns the Linux kernel’s lib/iov_iter.c and arises from an incorrect refcount fix for non-slab folio pages used in EROFS/v9fs p9 read paths. The root cause is that pages in a bvec can be coalesced across folio boundaries, and the non-slab folio refcount was not increased suffici...

CVE-2025-37779

In the Linux kernel, the following vulnerability has been resolved: lib/ioviter: fix to increase non slab folio refcount When testing EROFS file-backed mount over v9fs on qemu, I encountered a folio UAF issue. The page sanity check reports the following call trace. The root cause is that pages in...
