In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: core: Cancel RTC work during ufshcd_remove()
Currently, RTC work is only cancelled during __ufshcd_wl_suspend(). When
ufshcd is removed in ufshcd_remove(), RTC work is not cancelled. Due to
this, any further trigger of the RTC work after ufshcd_remove() would
result in a NULL pointer dereference as below:
Unable to handle kernel NULL pointer dereference at virtual address 00000000000002a4
Workqueue: events ufshcd_rtc_work
Call trace:
_raw_spin_lock_irqsave+0x34/0x8c
pm_runtime_get_if_active+0x24/0xb4
ufshcd_rtc_work+0x124/0x19c

worker_thread+0x144/0x280
kthread+0x11c/0x128
ret_from_fork+0x10/0x20
Since RTC work accesses the ufshcd internal structures, it should be cancelled
when ufshcd is removed. So do that in ufshcd_remove(), as per the order in
ufshcd_init().

CVE-2024-56582 Linux kernel (Low Latency) vulnerabilities
Title: Linux kernel (Low Latency) vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
Attila Szász discovered that the HFS+ file system implementation in the
Linux Kernel contained a heap overflow vulnerability. An attacker could use
a specially crafted file system image that, when mounted, could cause a
denial of service (system crash) or possibly execute arbitrary code.

CVE-2024-56621 [MEDIUM] CWE-476 kernel: scsi: ufs: core: Cancel RTC work during ufshcd_remove()
kernel: scsi: ufs: core: Cancel RTC work during ufshcd_remove()
In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: core: Cancel RTC work during ufshcd_remove()
Currently, RTC work is only cancelled during __ufshcd_wl_suspend(). When
ufshcd is removed in ufshcd_remove(), RTC work is not cancelled. Due to
this, any further trigger of the RTC work after ufshcd_remove() would
result in a NULL pointer dereference as below:
Unable to handle kernel NULL pointer dereference at virtual address 00000000000002a4
