CVE-2023-53521

The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:kernel/resource: fix kfree() of bootmem memory againSince commit ebff7d8f270d ( mem hotunplug: fix kfree() of bootmemmemory ), we could get a resource allocated during boot viaalloc_resource(). And it s required to release the resource usingfree_resource(). Howerver, many people use kfree directly which willresult in kernel BUG. In order to fix this without fixing every callsite, just leak a couple of bytes in such corner case.(CVE-2022-49190)

In the Linux kernel, the following vulnerability has been resolved:drivers: staging: rtl8723bs: Fix deadlock in rtw_surveydone_event_callback()There is a deadlock in rtw_surveydone_event_callback(),which is shown below: (Thread 1) | (Thread 2) | _set_timer()rtw_surveydone_event_callback()| mod_timer() spin_lock_bh() //(1) | (wait a time) ... | rtw_scan_timeout_handler() del_timer_sync() | spin_lock_bh() //(2) (wait timer to stop) | ...We hold pmlmepriv->lock in position (1) of thread 1 and usedel_timer_sync() to wait timer to stop, but timer handleralso need pmlmepriv->lock in position (2) of thread 2.As a result, rtw_surveydone_event_callback() will block forever.This patch extracts del_timer_sync() from the protection ofspin_lock_bh(), which could let timer handler to obtainthe needed lock. What`s more, we change spin_lock_bh() inrtw_scan_timeout_handler() to spin_lock_irq(). Otherwise,spin_lock_bh() will also cause deadlock() in timer handler.(CVE-2022-49309)

In the Linux kernel, the following vulnerability has been resolved:

drm/scheduler: fix fence ref counting

We leaked dependency fences when processes were beeing killed.

Additional to that grab a reference to the last scheduled fence.(CVE-2022-49829)

In the Linux kernel, the following vulnerability has been resolved:

kmalloc was called with mem_flags, which is passed down in cdns3_allocate_trb_pool() and have GFP_DMA32 flags. kmall_fix_flags() report warning.

GFP_DMA32 is not useful at all. dma_alloc_coherent() will handle DMA memory region correctly by pool->dev. GFP_DMA32 can be removed safely.(CVE-2022-50151)

In the Linux kernel, the following vulnerability has been resolved:

of: check previous kernel's ima-kexec-buffer against memory bounds

Presently ima_get_kexec_buffer() doesn't check if the previous kernel's ima-kexec-buffer lies outside the addressable memory range. This can result in a kernel panic if the new kernel is booted with 'mem=X' arg and the ima-kexec-buffer was allocated beyond that range by the previous kernel. The panic is usually of the form below:

$ sudo kexec --initrd initrd vmlinux --append='mem=16G'
