CVE-2021-47236

The Linux Kernel, the operating system core itself.

Security Fix(es):

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

net: cdc_eem: fix tx fixup skb leak

when usbnet transmit a skb, eem fixup it in eem_tx_fixup(), if skb_copy_expand() failed, it return NULL, usbnet_start_xmit() will have no chance to free original skb.

fix it by free orginal skb in eem_tx_fixup() first, then check skb clone status, if failed, return NULL to usbnet.(CVE-2021-47236)

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

gfs2: Fix use-after-free in gfs2_glock_shrink_scan

The GLF_LRU flag is checked under lru_lock in gfs2_glock_remove_from_lru() to remove the glock from the lru list in __gfs2_glock_put().

On the shrink scan path, the same flag is cleared under lru_lock but because of cond_resched_lock(&lru_lock) in gfs2_dispose_glock_lru(), progress on the put side can be made without deleting the glock from the lru list.

Keep GLF_LRU across the race window opened by cond_resched_lock(&lru_lock) to ensure correct behavior on both sides - clear GLF_LRU after list_del under lru_lock.(CVE-2021-47254)

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

netrom: Decrease sock refcount when sock timers expire

Commit 63346650c1a9 ("netrom: switch to sock timer API") switched to use sock timer API. It replaces mod_timer() by sk_reset_timer(), and del_timer() by sk_stop_timer().

Function sk_reset_timer() will increase the refcount of sock if it is called on an inactive timer, hence, in case the timer expires, we need to decrease the refcount ourselves in the handler, otherwise, the sock refcount will be unbalanced and the sock will never be freed.(CVE-2021-47294)

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

memory: fsl_ifc: fix leak of IO mapping on probe failure

On probe error the driver should unmap the IO memory. Smatch reports:

drivers/memory/fsl_ifc.c:298 fsl_ifc_ctrl_probe() warn: 'fsl_ifc_ctrl_dev->gregs' not released on lines: 298.(CVE-2021-47315)

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

watchdog: Fix possible use-after-free in wdt_startup()

This module's remove path calls del_timer(). However, that function does not wait until the timer handler finishes. This means that the timer handler may still be running after the driver's remove function has finished, which would result in a use-after-free.

Fix by calling del_timer_sync(), which makes sure the timer handler has finished, and unable to re-schedule itself.(CVE-2021-47324)

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

scsi: megaraid_sas: Fix resource leak in case of probe failure

The driver doesn't clean up all the allocated resources properly when scsi_add_host(), megasas_start_aen() function fails during the PCI device probe.

Clean up all those resources.(CVE-2021-47329)

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

ipack: ipoctal: fix module reference leak

A reference to the carrier module was taken on every open but was only released once when the final reference to the tty struct was dropped.

Fix this by taking the module reference and initialising the tty driver data when installing the tty.(CVE-2021-47403)

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

usb: dwc2: check return value after calling platform_get_resource()

It will cause null-ptr-deref if platform_get_resource() returns NULL, we need check the return value.(CVE-2021-47409)

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

i40e: Fix freeing of uninitialized misc IRQ vector

When VSI set up failed in i40e_probe() as part of PF switch set up driver was trying to free misc IRQ vectors in i40e_clear_interrupt_scheme and produced a kernel Oops:

Trying to free already-free IRQ 266 WARNING:…
