CVE-2020-36790 1 Linux 1 Linux Kernel 2026-06-17 N/A 5.5 MEDIUM

CVE-2020-36789 1 Linux 1 Linux Kernel 2026-06-17 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: can: dev: can_get_echo_skb(): prevent call to kfree_skb() in hard IRQ context If a driver calls can_get_echo_skb() during a hardware IRQ (which is often, but not always, the case), the 'WARN_ON(in_irq)' in net/core/skbuff.c#skb_release_head_state() might be triggered, under network congestion circumstances, together with the potential risk of a NULL pointer dereference. The root cause of this issue is the call to kfree_skb() instead of dev_kfree_skb_irq() in net/core/dev.c#enqueue_to_backlog(). This patch prevents the skb to be freed within the call to netif_rx() by incrementing its reference count with skb_get(). The skb is finally freed by one of the in-irq-context safe functions: dev_consume_skb_any() or dev_kfree_skb_any(). The "any" version is used because some drivers might call can_get_echo_skb() in a normal context. The reason for this issue to occur is that initially, in the core network stack, loopback skb were not supposed to be received in hardware IRQ context. The CAN stack is an exeption. This bug was previously reported back in 2017 in [1] but the proposed patch never got accepted. While [1] directly modifies net/core/dev.c, we try to propose here a smoother modification local to CAN network stack (the assumption behind is that only CAN devices are affected by this issue).

CVE-2020-36786 1 Linux 1 Linux Kernel 2026-06-17 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: media: [next] staging: media: atomisp: fix memory leak of object flash In the case where the call to lm3554_platform_data_func returns an error there is a memory leak on the error return path of object flash. Fix this by adding an error return path that will free flash and rename labels fail2 to fail3 and fail1 to fail2.
CVE-2020-36784 1 Linux 1 Linux Kernel 2026-06-17 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: i2c: cadence: fix reference leak when pm_runtime_get_sync fails The PM reference count is not expected to be incremented on return in functions cdns_i2c_master_xfer and cdns_reg_slave.
