[PATCH openEuler-1.0-LTS] io_uring: truncate lengths larger than MAX_RW_COUNT on provide buffers
by Yang Yingliang 27 May '21

27 May '21

From: Thadeu Lima de Souza Cascardo <cascardo(a)canonical.com> mainline inclusion from mainline-v5.13-rc1 commit d1f82808877bb10d3deee7cf3374a4eb3fb582db category: bugfix bugzilla: NA CVE: CVE-2021-3491 -------------------------------- Read and write operations are capped to MAX_RW_COUNT. Some read ops rely on that limit, and that is not guaranteed by the IORING_OP_PROVIDE_BUFFERS. Truncate those lengths when doing io_add_buffers, so buffer addresses still use the uncapped length. Also, take the chance and change struct io_buffer len member to __u32, so it matches struct io_provide_buffer len member. This fixes CVE-2021-3491, also reported as ZDI-CAN-13546.

[PATCH openEuler-1.0-LTS 1/4] net/nfc: fix use-after-free llcp_sock_bind/connect
by Yang Yingliang 26 May '21

26 May '21

From: Or Cohen <orcohen(a)paloaltonetworks.com> stable inclusion from linux-4.19.191 commit 48fba458fe54cc2a980a05c13e6c19b8b2cfb610 CVE: CVE-2021-23134 -------------------------------- commit c61760e6940dd4039a7f5e84a6afc9cdbf4d82b6 upstream. Commits 8a4cd82d ("nfc: fix refcount leak in llcp_sock_connect()") and c33b1cc62 ("nfc: fix refcount leak in llcp_sock_bind()") fixed a refcount leak bug in bind/connect but introduced a use-after-free if the same local is assigned to 2 different sockets. This can be triggered by the following simple program: int sock1 = socket( AF_NFC, SOCK_STREAM, NFC_SOCKPROTO_LLCP ); int sock2 = socket( AF_NFC, SOCK_STREAM, NFC_SOCKPROTO_LLCP ); memset( &addr, 0, sizeof(struct sockaddr_nfc_llcp) ); addr.sa_family = AF_NFC; addr.nfc_protocol = NFC_PROTO_NFC_DEP; bind( sock1, (struct sockaddr*) &addr, sizeof(struct sockaddr_nfc_llcp) ) bind( sock2, (struct sockaddr*) &addr, sizeof(struct sockaddr_nfc_llcp) ) close(sock1); close(sock2); Fix this by assigning NULL to llcp_sock->local after calling nfc_llcp_local_put. This addresses CVE-2021-23134.

[PATCH kernel-4.19 1/2] x86/apic/vector: Force interupt handler invocation to irq context
by Yang Yingliang 26 May '21

26 May '21

From: Thomas Gleixner <tglx(a)linutronix.de> mainline inclusion from mainline-5.7 commit 008f1d60fe25810d4554916744b0975d76601b64 category: bugfix bugzilla: NA CVE: NA ------------------------------------------------- Sathyanarayanan reported that the PCI-E AER error injection mechanism can result in a NULL pointer dereference in apic_ack_edge(): BUG: unable to handle kernel NULL pointer dereference at 0000000000000078 RIP: 0010:apic_ack_edge+0x1e/0x40 Call Trace: handle_edge_irq+0x7d/0x1e0 generic_handle_irq+0x27/0x30 aer_inject_write+0x53a/0x720 It crashes in irq_complete_move() which dereferences get_irq_regs() which is obviously NULL when this is called from non interrupt context. Of course the pointer could be checked, but that just papers over the real issue. Invoking the low level interrupt handling mechanism from random code can wreckage the fragile interrupt affinity mechanism of x86 as interrupts can only be moved in interrupt context or with special care when a CPU goes offline and the move has to be enforced. In the best case this triggers the warning in the MSI affinity setter, but if the call happens on the correct CPU it just corrupts state and might prevent further interrupt delivery for the affected device. Mark the APIC interrupts as unsuitable for being invoked in random contexts. This prevents the AER injection from proliferating the wreckage, but that's less broken than the current state of affairs and more correct than just papering over the problem by sprinkling random checks all over the place and silently corrupting state.
