https://notcve.org/view.php?id=CVE-2024-43822
In the Linux kernel, the following vulnerability has been resolved: ASoc: PCM6240: Return directly after a failed devm_kzalloc() in pcmdevice_i2c_probe() The value “-ENOMEM” was assigned to the local variable “ret” in one if branch after a devm_kzalloc() call failed at the beginning. This error code will trigger then a pcmdevice_remove() call with a passed null pointer so that an undesirable dereference will be performed. Thus return the appropriate error code directly. • https://git.kernel.org/stable/c/1324eafd37aa5c5b970c1b48a857acc81f0685c8 https://git.kernel.org/stable/c/fa6f16eff7320c91e908309e31be34cbbe4b7e58 https://git.kernel.org/stable/c/3722873d49a1788d5420894d4f6f63e35f5c1f13 •

https://notcve.org/view.php?id=CVE-2024-43821
In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Fix a possible null pointer dereference In function lpfc_xcvr_data_show, the memory allocation with kmalloc might fail, thereby making rdp_context a null pointer. In the following context and functions that use this pointer, there are dereferencing operations, leading to null pointer dereference. To fix this issue, a null pointer check should be added. If it is null, use scnprintf to notify the user and return len. • https://git.kernel.org/stable/c/479b0917e4477f49df2e3be454aac3cfa5dec171 https://git.kernel.org/stable/c/57600a7dd2b52c904f7c8d2cac0fd8c23868e680 https://git.kernel.org/stable/c/45b2a23e00d448a9e6d1f371ca3a4d4b073fe78c https://git.kernel.org/stable/c/5e0bf3e8aec2cbc51123f84b29aaacbd91fc56fa •

https://notcve.org/view.php?id=CVE-2024-43820
In the Linux kernel, the following vulnerability has been resolved: dm-raid: Fix WARN_ON_ONCE check for sync_thread in raid_resume rm-raid devices will occasionally trigger the following warning when being resumed after a table load because DM_RECOVERY_RUNNING is set: WARNING: CPU: 7 PID: 5660 at drivers/md/dm-raid.c:4105 raid_resume+0xee/0x100 [dm_raid] The failing check is: WARN_ON_ONCE(test_bit(MD_RECOVERY_RUNNING, &mddev->recovery)); This check is designed to make sure that the sync thread isn't registered, but md_check_recovery can set MD_RECOVERY_RUNNING without the sync_thread ever getting registered. Instead of checking if MD_RECOVERY_RUNNING is set, check if sync_thread is non-NULL. • https://git.kernel.org/stable/c/16c4770c75b1223998adbeb7286f9a15c65fba73 https://git.kernel.org/stable/c/af916cb66a80597f3523bc85812e790bcdcfd62b https://git.kernel.org/stable/c/eaa8fc9b092837cf2c754bde1a15d784ce9a85ab https://git.kernel.org/stable/c/a5c15a78c0e1631b7df822b56e8b6424e4d1ca3e https://git.kernel.org/stable/c/3199a34bfaf7561410e0be1e33a61eba870768fc •
CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2024-43819 – kvm: s390: Reject memory region operations for ucontrol VMs
https://notcve.org/view.php?id=CVE-2024-43819
In the Linux kernel, the following vulnerability has been resolved: kvm: s390: Reject memory region operations for ucontrol VMs This change rejects the KVM_SET_USER_MEMORY_REGION and KVM_SET_USER_MEMORY_REGION2 ioctls when called on a ucontrol VM. This is necessary since ucontrol VMs have kvm->arch.gmap set to 0 and would thus result in a null pointer dereference further in. Memory management needs to be performed in userspace and using the ioctls KVM_S390_UCAS_MAP and KVM_S390_UCAS_UNMAP. Also improve s390 specific documentation for KVM_SET_USER_MEMORY_REGION and KVM_SET_USER_MEMORY_REGION2.

In the Linux kernel, the following vulnerability has been resolved: ASoC: amd: Adjust error handling in case of absent codec device acpi_get_first_physical_node() can return NULL in several cases (no such device, ACPI table error, reference count drop to 0, etc). Existing check just emit error message, but doesn't perform return. Then this NULL pointer is passed to devm_acpi_dev_add_driver_gpios() where it is dereferenced. Adjust this error handling by adding error code return.
