Linux kernel security vulnerabilities

Linux kernel is the kernel used by the Linux Foundation's open source operating system Linux. A security vulnerability exists in the Linux kernel, which originates in the lpfc driver module under the scsi subsystem, where the lpfcworkerwakeup function is called while holding a hbalock lock...

SUSE CVE-2021-47183

In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Fix link down processing to address NULL pointer dereference If an FC link down transition while PLOGIs are outstanding to fabric well known addresses, outstanding ABTS requests may result in a NULL pointer dereferenc...

DEBIAN-CVE-2021-47203

In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Fix listadd corruption in lpfcdraintxq When parsing the txq list in lpfcdraintxq, the driver attempts to pass the requests to the adapter. If such an attempt fails, a local "failmsg" string is set and a log message...

CVE-2021-47203

CVE-2021-47203 concerns the Linux kernel SCSI lpfc driver. The description details a corruption in the lpfc_drain_txq() path where, if an adapter send fails, a local fail_msg is set and jobs are added to a completions list. Processing of subsequent jobs continues, and because fail_msg remains set...

CVE-2021-47045

In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Fix null pointer dereference in lpfcprepelsiocb It is possible to call lpfcissueelsplogi passing a did for which no matching ndlp is found. A call is then made to lpfcprepelsiocb with a null pointer to a lpfcnodelist...

CVE-2024-24855 Race condition vulnerability in Linux kernel scsi device driver lpfc_unregister_fcf_rescan()

A race condition was found in the Linux kernel's scsi device driver in lpfcunregisterfcfrescan function. This can result in a null pointer dereference issue, possibly leading to a kernel panic or denial of service issue...

kernel: scsi: lpfc: Check kzalloc() in lpfc_sli4_cgn_params_read()

In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Check kzalloc in lpfcsli4cgnparamsread If kzalloc fails in lpfcsli4cgnparamsread, then we rely on lpfcreadobject's routine to NULL check pdata. Currently, an early return error is thrown from lpfcreadobject to protect...

kernel: scsi: lpfc: Fix null ndlp ptr dereference in abnormal exit path for GFT_ID

In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Fix null ndlp ptr dereference in abnormal exit path for GFTID An error case exit from lpfccmplctcmdgftid results in a call to lpfcnlpput with a null pointer to a nodelist structure. Changed lpfccmplctcmdgftid to...

kernel: Linux kernel: Hard lockup in lpfc driver leads to Denial of Service

A flaw was found in the Linux kernel. A local user could trigger a hard lockup by concurrently reading the rxmonitor from debugfs during I/O operations in the lpfc driver. This concurrency issue, caused by insufficient spin lock protection, leads to a system crash and results in a Denial of Servi...

PT-2025-37887

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The Linux kernel contains a use-after-free flaw within the lpfc wr object routine during the sysfs firmware write process. The driver accesses data through a pointer wr object after th...

kernel: scsi: lpfc: Fix call trace observed during I/O with CMF enabled

A vulnerability has been identified in the lpfc module within the Linux kernel. This flaw occurs because the driver attempts to access per-CPU data from a preemptible context using an incorrect function. This improper handling of critical data can lead to system instability and result in a...

kernel: scsi: lpfc: Fix possible memory leak when failing to issue CMF WQE

A flaw was found in the lpfc module in the Linux kernel. A missing release of allocated memory when an error occurs will cause a memory leak, potentially impacting system performance and resulting in a denial of service...
